Unfortunately vga= doesn't work with grub2 (it's deprecated). Did you manually reinstall grub1 or just refuse to install grub2 when prompted?. I tried some suggested grub2 alternatives (eg set gfxpayload=keep in /etc/grub.d/00_header and setting GRUB_GFXMODE in /etc/default/grub) but it didn't fix the problem.

FWIW, I also get the screen corruption when I suspend, resume, and shut down, ie whenever it switches out of the CTRL-ALT-F7 console.

I have tried the vanilla 2.6.31.3 kernel and it also has the problem. At that point I thought it might be a grub2 issue but if grub1 also has it, perhaps it's an xserver problem? I'll try an older kernel to see if that fixes it.
