Having read http://keithp.com/blogs/Sharpening_the_Intel_Driver_Focus I am even more confused now - it's clear that Ubuntu should not have upgrading *anything* to do with intel graphics untill the guys over there had a chance to finish things up, probably mainly "A minor but important piece of this work is to get UXA running without GEM so that we have EXA-like performance on older kernels" so that UXA can be made the default without kiling performance.
These changes to the intel driver are obviously 'in flight' and should have been postponed to 9.10.
