simple mechanism for configuring itself and what it passes on to what follows. Grub2 needs neither vga= nor video=. AFAICT, it doesn't pass vga=, and even if it does, KMS overrides it. What it does or not with video= I don't know. I don't use Grub2 much, and not at all with openSUSE.
I have an old laptop that does need "vga=791" in grub2, or it doesn't work correctly :-P
With what gfxchip, ATI Rage*? Cirrus Logic? Matrox? Trident? Many old gfxchips have no KMS support, so vga= remains useful for them.

If I remember correctly, you helped me to set it up some years ago. I don't remember all the issues I had with it. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
