And as you can see the screen gets found incorrectly, in Windows it can handle: 1280 X 800, 1280x768, 1280x720 and 1024x768

And in windows the screen is set as 1280x800 - but in linux 800x1280 - maybe this is where everything go wrong.
Hi insomniac - I have recently been troubleshooting video limitations on some of my machines and it apears to be possible using xrandr to create new "modelines" that allow X to use different resolutions that were previously unavailable.

I followed a couple of Ubuntu tutorials with some success and thought you might be interested in the links:

http://www.ubuntugeek.com/how-change-display-resolution-settings-using-xrandr.html

http://askubuntu.com/questions/19954/how-to-set-the-monitor-to-its-native-resolution-which-is-not-listed-in-the-resol

The technique basically seems to be:
- Generate (request) the modeline data
- Copy the modeline data and enter it into xrandr with --newmode argument
- Make the new modeline available to the video output device with xrandr --addmode argument
- Use xrandr to attach the modeline to the output device

I had to follow the examples (and some other similar ones) a couple of times to understand it but I did succeed in using a non standard resolution in the end. Don't know if it would work for your device though....

Insomniacno1 put his finger on a real hassle Linux-wide about the lack of bluetooth (and touchscreen?) functionality in the bootup/boot manager stage of distros, here http://www.murga-linux.com/puppy/viewtopic.php?p=926058#926058

...It would be nice with a bootparameter or built-in to the iso, that bluetooth were enabled by default and accepted connections without pairing code. It that were possible then bluetooth keyboard/mouse could be used immediately.

Any chance someone could make an iso like that?

...and I'm digging through the threads now to see if/how workable solutions to the OP and related Puppy-tablet issues have been addressed...
