Ok, so it seems pretty clear at this point this was a driver bug with the intel driver and i915 hardware but as natty should already have what you're getting from the x-updates PPA I'm going to mark this as fixed. Thanks to Max and Omer for willing to get a little more bleeding edge to confirm the fix.
