Binary package hint: grub2
on my T400 I get a flashing and corrupted screen in grub.
grub is still functional, just without usable display.
setting the following in /etc/default/grub gets readable screen.

This is happening because the VBE BIOS advertises a 1440x900x32 mode (and even advertises 1440x900 as the best mode, though I don't think EDID is specific about the preferred depth) but fails to program it correctly. I don't know what the best solution to this is as yet.
