Ian,
Andreas has also tried loading Maya and has seen similar problems. He
elluded to Maya wanting an overlay visual. If would be interesting to
see if the vis == NULL problem went away if we had an overlay visual.
We could hack up the visual initialization code to lie and say we had
overlay visuals, just to see if this is the problem...

If you create a virtual 1280x1024 desktop, does this problem go away?
