Did some more testing of the vgabios today, two issues popped up:
(1) screen isn't cleared in some cases. Visible with grub1 in text mode. When it displays the menu a few stray chars are visible. Even more obvious it becomes when hitting 'c' then to get a prompt, then alot of the menu is still visible.
Thanks. Can you point me to an image and/or the steps to reproduce? I've tracked down a few of these before, and I'm sure I can fix it if I can reproduce it.
Install fedora 15 (or older) in qemu (mimimal is enougth). Edit /boot/grub/menu.lst and comment out the splashimage and hiddenmenu lines. On next reboot grub will come up in text mode and you'll see the behavior described above.
I couldn't reproduce the issue on the initial screen, but I can reproduce when hitting the 'c' key. Turns out to be an integer overflow issue - patch below.
