The vesa driver was using a resolution of 1280x1024x32... is there a
way to get a whole modeline out of that?

I'm assuming the clock is at fault, yes.

Compiling on my home system overnight (these atom boards are pretty
slick, but slow as dirt at compiling the kernel). I've got a
different monitor at home to try, so we'll see what happens. How do I
hand set the mode that gma500 uses?
