Maximum CPU scaling frequency incorrectly set while in Xorg

Bug Description

Today I noticed that my new Maverick installation is substantially slower than it ought to be. Looking around, I found that cpufreq's maximum frequency was set substantially lower than it ought to be,

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

After switching to a VT, I noticed that the maximum frequency had been changed to its sane value,

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

After switching back to Xorg, however, the value had been reverted to 800MHz.

I have no idea what process is causing this behavior. I have tried killing both upowerd and gnome-power-manager to no avail.
