Intel + GEM + suspend -> fail

[Peter Clifton]

If it's a known issue, fine, well and good.. otherwise let me know and
I'll dig you out some more info as to the exact config, and see if I can
be useful about getting this fixed.

2.6.28 kernel + patch + patch "drm/i915: Don't return busy for buffers
left on the flushing list."

Intel driver: d8e89b26ef5ef2c15e5d34162b14d279a7f0bb1c (I think!)
Mesa: d9b92b112fb64005c71edf1158f7dffabc4659bb
