2.6.35-rc2 completely hosed on intel gfx?

[Norbert Preining]

Dear everyone,

(please cc)

I just switched from 2.6.35-rc1 to rc2 and that hosed several things,
all seemingly related to intel graphics card driver:
- suspend suddenly hangs completely on switch, no traces found, not
  even sysrq was working
- X often (not 100%) hangs wihth a fix cursor (not blinking) on the 
  to left corner, I got a stack trace in my syslog for that:

general protection fault: 0000 [#1] PREEMPT SMP
