I got hangs at resume on my ThinkPad X61s with i965 graphics and
non-modular i915 driver. I got the hangs after suspend to RAM and
suspend to disk using TuxOnIce, but not every time. I reverted the 
commit metioned by Pedro and wasn't able to reproduce the hang after
several suspend cycles.

I'll also try the attached patch.

Tino
