I tested the Balloon3D software renderer a while ago and it worked,
albeit rather slowly. Might have been a B2 machine though, the new
CPUs are faster.
As a data point, Doom runs quite fast even at full resolution on a
B4. Have not heard reports on getting Quake running. But I suspect
that a software renderer hand-optimized towards the XO could be made
to work at decent frame rate.
