The base revision should be 0.8 iirc, so its the latest one released
from scitechsoft. (BTW, does anyone know why scitech put it to
"obsolete"?)

There are some patches in our tree that are potentially missing in the
X.org tree and a lot more patches are missing the other way round.

Yes, the bios emulation in our setup is absolutely minimal, most stuff
is commented out. So we really only emulate the PCI interrupt 1a. No
surprise lots of cards don't work that work in X..

Yes, it has on mine, and on Egbert's (Egbert Eich from the FreeDesktop
project, CCed) as well.. I already set up a development repository for
that a couple of years ago, but we never got to work on that any
further. 

Another thing is still we should go vm86 mode instead of x86 emulation.
X.org does the same and they're successful with it.
