Re: New Laptop: i810: HELP

Umm, here's a really stupid and probably unworkable idea that i know 
absolutely nothing about :-)

there is something that i have read about called the 'framebuffer' 
driver, it's supposedly chipset independent. 

perhaps that is an avenue you could pursue?

the other point worth mentioning is that if you managed to get 320x200,
you probably can get at least 640x480 and maybe 800x600 by continuing to
fiddle about....
