Chris, I'll be happy to try it, but I don't see how it could have any bearing
on the problem at hand. RC6 is disabled on my machine via a kernel boot option
(i915.i915_enable_rc6=0) because of the instability.

I'll be quite happy to re-enable RC6, but a patch tuning RC6 can't really fix
the resume-from-disk problem when RC6 isn't even enabled. Can it?
