UXA on 2.6.3 changed nothing compared to EXA. glxgears performance is
down slightly. No change to video viewing. CPU usage is still 8% when
running top (too much CPU for redrawing the text there, I suppose).
Spikes up to 50% when viewing a webpage using Firefox. No change to
values in powertop eith

worse. The bootm line is that cpu usage was minimal on 8.10, and
immediately on upgrade to 9.04, the X process's cpu usage shot up to a
time average of about 50% of one core (of a 2.0 GHz Core2Duo, 4 MB L2).

Richard, would you mind testing if the issue still occurs with UXA on
the 2.6.3 driver?
Since you see the issue go away by going to 2.4, while others didn't, it
sounds like they may be having a separate problem.
