Its under uClibc-0.9.27...
asm/wm86.h do have a
#define IF_MASK 0x00000200
but no X86_EFLAGS

I was looking into using the "xcompmgr" with jwm to create some "cheep & cool" visuals...I will try again to get the composite introduced in the present code.
And after a second trial I think I will not want composite in here anyway - explodes in demand for xfixes, damage and undefined things.
And you are right - kdrive + composite is in Xorg1.2-1.4 - thanks!

I was looking at my C notes and see that vm86 is a syscall
http://linux.die.net/man/2/vm86

#include <syscall.h>
#include <sys/vm86.h>
int vm86(unsigned long fn, struct vm86plus_struct *v86){
return syscall(SYS_vm86,fn,v86);
}

(the older xvesa may need vm86old though?)

I've been seriously considering setting up my fast boot C implementation as a full time project if any pupngoers are interested, but only to mount the file systems, set some environment variables and start basic X... leaving the b.s. stuff that distro builders often change to be done inside X.

This will require several kernel parameters to be set such as:
mounts=/dev/sda1:ext3,/dev/sda2:ext4
swap=/mnt/sda1/pupngo/pupngo.swp #or /dev/sd[a-z][1-9]*
unions_ro=/mnt/sda1/pupngo/pup.sfs,/mnt/sda1/pupngo/devx.sfs
#unions will be layered in order they appear
union_rw=/mnt/sda1/pupngo/save.4fs
X=Xorg #can be Xvesa, xfbdev,... or something else entirely
Xscreen=640x480x16 #used by Xvesa -screen, todo accept "max"
LANG=en_US #any supported language
kb=us #any supported kb config
desktop=rox #none, jwm, pcmanfm, thunor, idesk, gnome, kde, ...
wm=jwm #icewm, mcwm, xdm, gdm, slim ... (window/display manager)
other parameters matching var=value will be set as env variables

This shouldn't be too difficult to accommodate in the installer, since the variables set in the gtkdialog wrapper can be used when writing the menu.cfg (or whatever gui/bootloader combo is chosen) ... the boot cd can have a set(s) of default parameters

possible future params:
user=root #spot, ... user defined?
toram=all # all=load all sfs in ram, 1 (only first sfs) 2, 3,... ?
module_dir=/lib/modules/3.8
modules=subdir_path/somemodule.ko,.../another.ko
#note, modules needed for boot should be builtin if possible ... the 3.8 kernel makes it much easier to load modules using only the filename without needing to memmap the file first (finit_module could be backported)

Normal init processes have the ability to halt, shutdown and reboot. I was thinking this could be set up by reading a file or fifo in a loop at the end of the init that could be written to by simply echoing to /tmp/.init ... thus the traditional command to shutdown/restart: init 6 ... could be emulated by echo $1 > /tmp/.init

I am trying to keep everything as libc independent as possible, to the point of writing my own implementations of many standard functions like fprintf, printf, strlen, strcmp, strncmp (todo: fork and exec* via syscalls)

Well, debug time for me.
I have X starting, fonts and mouse working...but NOT keyboard.
Instead, xev tells me the right keycode but "keysym NoSymbol, 0x0".

EDIT:
It seems you can use xmodmap, so I went:

@technosaurus: I'm in - I might only be able to contribute with testing your stuff.
@Ibidim: I do not have git - tried to compile it from source but failed. Then tried a pet found here but I miss some libs. Then got the sources as zip-files but couldn't find the g_hack. Anyway installed musl, tinyxlib & tinyxserver. While compiling tinyxserver got stuck in
/hw/kdrive/linux/agp.c - missing headers in asm and linux - supplied that from main system but got conflicting types for 'fd_set/dev_t/ino_t/mode_t/nlink_t/off_t/suseconds_t/timer_t/uid_t/gid_t...

I really would like to use musl but I seem to get stuck with something when I try...Any hints to get further?

[technosaurus]

when I was building musl it helped to edit the musl-gcc wrapper to add defines for xopen, bsd and gnu source.

[goingnuts]

ok got it. Did the above things and got same errors. If added -D__KERNEL_STRICT_NAMES to xserver standard_definitions.mk it builds - missed libz but after that it links. I haven't tested yet if it runs - must postpone that till tomorrow. My kernel is 2.6.25.16. The -D__KERNEL_STRICT_NAMES bypasses all the conflicting stuff in /linux/types.h...

[Ibidem]

OK, good to know about that little bit. I guess the kernel headers got stricter later in the 2.6 series.
Do you know whether adding -D__KERNEL_STRICT_NAMES works with your version of uclibc?

(I'm considering adding that to the default CFLAGS.)

also, about git:
Minimum "full-featured" build requires gettext/libintl (recommended; it's a real pain to workaround, but is possible), libcurl (http fetch), and probably perl as well. You may also want OpenSSL for pulling over https, in which case curl must be linked with openssl also; expat is only for http(s) push.
You need to edit the Makefile for git or set variables in the make command.
eg, bare minimum/no curl but gettext, libintl, and perl (with libintl-perl module) are installed:

Xvesa musl build works. Seems -D__KERNEL_STRICT_NAMES works with uclibc too. I will try a new git-build this afternoon.
Update: Got the git to build static - would have liked to post it but forum seems to allow max 256K attachments atm.
20130209: attached minor patch (diet libc build/removed some warnings/some errors in respecting standard_definitions.mk in makefiles)

Finally managed to build a Xvesa with the composite extension. Used below modified script where original is here:
