Xorg segfaults on i915gm during intel_drv.so init

[Michal Suchanek]

Hello,

this worked well enough just before 1.12 when I wrote that patch  but
X master has changed too much I guess.

Anyway, I tested with 1.12.0 and without the patch the X server
crashes on reset with rotated screen.

With the patch it does not crash for me but I start without rotation
and only add it through session startup scripts. Maybe setting up
rotation in xorg.conf triggers the other crash.

However, applying the patch uncovers another bug. When the X server
resets it displays garbage.

Thanks

Michal
