I have implemented a new grub command (setvbe) which can be used to
switch the graphics mode before booting. It can take arguments like
setvbe 1024x768x32 (scans the video modes for a suitable one) (*)
setvbe 0x118 (set mode 0x118)
(*) it does not use the video mode list as used by vbeprobe because this
method doesn't work on some systems, specially on qemu.
It will add a command line option "video=" to the booted kernel,
passing some arguments needed by the loaded kernel.
I started using GRUB Legacy 0.97's source code for this, but now I'm
using grub_for_dos 0.41 (0.42 did not work for me) which uses GRUB
Legacy 0.97. I think the newer and more mantained version of GRUB Legacy
is that one (grub 4 dos). Which includes lots of cool new features.
If anybody's interested, I can send it personally or to the list.
