Sounds like this might be going to be a fix for the Hyper-Z issues.
And I think AMD is trying to do it the right way, it's just that they're not as big as intel and they had to split up devs in 2 sections: An fglrx team and a "free team". And they had to catch up a lot with the free driver. Support is coming faster now, so one can hope that with the next generations (if there aren't big HW changes) some basic support or better might be available on HW release day.
Furthermore, intel doesn't have a binary blob to do or to compare with (let aside this relabeled imgtec stuff... omg).
