I'm not sure if you are aware, but you are mailing the -developers mailing list.

Since you're here and appear to be one of only two people that care about this 
issue, I would suggest that you read up on oprofile and find where the problem 
is - Myth code, QT, X11 or the driver for your card are all possibilities.

You'll have to recompile all of the above with symbols then run an oprofile 
enabled kernel to track down the processor usage.
