I suppose you uses LynxEM+ SM712 chip in your system. It’s
true that SM712 only has 4MB VRAM. So it can’t be configured to 1024x1024
virtual mode in XRandR mode.
You can try to add “ Virtual 1024 768” into “Screen” section.

Done. I put whole "Screen"
section with both 16bit and 24bit "Display"
subsections. Both have only 1024x768 mode defined. I found on page
linked from gNewSense wiki[1] that this machine has only 4MB VRAM
(detected by X.org). Is that true? The other problem may be ModeLine,
but I'm not brave enough to "guess" it and put hardcoded value into
conf
file ;) I don't know if anyone has problems with "flickering" and so
on,
but if so, then someone more skilled with access to the hardware would
check it (with xvidtune?). I don't know however if such experiments are
safe for the hardware ;)

Happy hacking!
