Well, I have 2 VESA Text modes in the list if tell the kernel "vga=ask"
and the kernel tells me that i have a vesa card in the headline of
"vga=ask" (but i don't know if this means that it is a VESA 2.0 card
which supports a linear frame buffer). The code after the "check_vesa"
mark in linux/arch/i386/boot/video.S just returns if the mode is ok or
not - what's about a more verbose message? ("badmdt" does not tell
anything except that it does not work. :-)
But I guess that the S3 Virge card is VESA 2 compatible (it's not a very
old card). I can't find any manuals - so I'm not absolute sure about this.
How can I find out if I can use my card or not?

PS: Why is all this stuff written in pure assembler?
It's so hard to read. :-)
