Subject description: SiliconMotion driver doesn't work...

I have a Panasonic Toughbook Cf-37 that I'm trying to convert to a fully Puppy driven machine. My biggest hurdle so far has been figuring out whats wrong with the video. I can use XVESA but if I want to use a plain command line I get a lovely garbled output (I'd post a picture but I can't find my camera). I thought switching to Xorg might make a difference, but Xorg won't load or if it does, the mouse rendering is so screwed up that it's almost useless.

The video card is a Silicon Motion SM710 LynxEM. The monitor is an 800x600 LCD with a 60Hz to 75Hz refresh ( i think). If I can get this working I'll move on to the touch screen. THanks in advance.

Here's what my xorg.conf looks like
#Special base config file used in Puppy Linux.

# **********************************************************************
# Module section -- this  section  is used to specify
# which dynamically loadable modules to load.
# **********************************************************************
Section "Module"
   Load "synaptics"

# This loads the DBE extension module.

    Load        "dbe"     # Double buffer extension

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
    SubSection  "extmod"
      Option    "omit xfree86-dga"   # don't initialise the DGA extension

# This loads the font modules
    Load        "type1"
    Load        "freetype"

# This loads the GLX module
    Load       "glx"

# This loads xtrap extension, used by xrandr
    Load       "xtrap"


# **********************************************************************

# **********************************************************************

Section "Files"

# The location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.

    RgbPath   "/usr/X11R7/lib/X11/rgb"

# Multiple FontPath entries are allowed (which are concatenated together),

Section "ServerFlags"

# Uncomment this to disable the <Crtl><Alt><Fn> VT switch sequence
# (where n is 1 through 12).  This allows clients to receive these key
# events.

#    Option "DontVTSwitch"

# Enables mode switching with xrandr
# There is a report that this can cause Xorg not to work on some
# video hardware, so default is commented-out...

After some searching I ended up in many places and now Xorg at least loads.

Places I ended up:
die.net man(4) page
Xfree86 man(4) page
A forum post about a ASUS L7300
A post for the same laptop on the Ubuntu Forums

However, I still have the annoying triple cursor issue. And now instead of a corrupted console after quitting X, there is no console.

my xorg.conf device section now looks like this:

Section "Device"
      Identifier "Card0"
      ChipSet "lynxem"
      VendorName "Silicon Motion, Inc."
      BoardName "SM710 LynxEM"
      BusID "PCI:0:2:0"
      Option "HWCursor" "ON"
      Option "UseBIOS" "ON"
      Option "NoAccel"
      Option "No MTRR"

also, here is what puppy has for the interfaces:
