I can't reproduce the issue with no display until VT switch anymore, so
clearly I was mistaken or it's been solved by a different commit
meanwhile, or it just doesn't happen all that often and the idea of
crash being better than confusing picture for most people doesn't hold
anymore. So I've pushed this trivial segfault fix to GIT now, to be part
of 2.11.9.

I don't suggest using NoAccel though, as it loses XVideo and many other
non-acceleration (read non-deceleration) related things too.

Have you tested rotation (and rotation + Xv) with current GIT code on
the older xserver-1.6 found in FC-11 and XO-1 builds?

Regards,
Mart
