We've already got that working: Ove Kaaven had modified DXEGEN to output
a VBE/AF driver format, and I'm right now in the middle of filling in
all the API routines. I'm just making a dummy driver that sits on top of
VESA, translating VBE/AF calls into their VESA equivalents, so other
people can later just replace my VESA calls with chipset-specific code.

It seems to be working quite well: it can already set a 640x480 mode
from the Allegro test.exe, and the SciTech vbetest program is able to
load my driver and find out what modes it supports, but then crashes
whenever it tries to set a video mode :-) Hopefully I'll have a finished
version by the middle of next week, at which point people can start
modifying it to support individual cards.
