I still don't know what's the best way to handle that one... the bug is
in X and I don't see a way to work around it without removing support
for legacy memory access from the kernel :-( Or doing it in a way that
doesn't allow userspace to differenciate between the kernel not
supporting it vs. the HW not supporting it, causing X to fallback to
even more broken crap.

I'll try to find out the extent of the X problem and whether that's
fixable in a way that can hit distros.
