Your might have a different issue or perhaps you should make sure you're up to date with the latest git pull. I'm on 14c62e78dc1379185515be41903c4a667efc6d54 (3.1.0-rc3)
I'm using Lenovo X201s and X was very very unstable and screen freezes after a while. Now after adding i915.i915_enable_rc6=1, X is running happily again!!!
Thanks, Jeff.
