It seems that the Ubuntu maintainer thinks it better that I push upstream as I understand the issue (from a users POV) better than he. I misunderstood that. He assured me they are already aware of this missing feature. I just wish they hadn't dropped it completely before a new method was put in place.

You were referring to http://en.wikipedia....Execution_Manager ? The Wikipedia page is short on detail, but it looks like the people who know the hardware inside out (not just Intel) have decided to just fix X.org's code problems rather than wait for someone else to think up a solution.
