Based on the original patch by Christoph Bumiller, but since it depends on kernel support patched I cannot push it yet. The changes are that I enable vblank by default, and offset takes OFFSET_HIGH/LOW instead of something relative to notifier_bo.

Hi there, Resending these now that they've had some more polish and testing, and I heard that Ben's vacation is over :-) These patches work as a starting point for more explicit error mechanisms and better robustness.
