Debatable. Might be triggered by hardware being slightly off spec. BenH
had me test a variety of things, with the final solution (presumably
what's in 2.6.11 now) getting the timing right about 99% of the time.
Part of the solution was to activate the UseFBDev X option, at that time.
Forgot to mention that; Ben was going to get a proper fix into X - I
didn't check that.
