Have any of you who have been trying 2.6.34rc3-51 experienced Xorg using abnormally much CPU time? With an idle (KDE) desktop, it seems to be consuming 10-30 times more CPU than with 2.6.32-22. It's hard to get an accurate measurement, but it's certainly qualitatively enough for my laptop's CPU fan to spin up periodically when the computer is just sitting there unused. This did not happen with 2.6.32-22 and earlier.
