Description of problem:
On my Santa Rosa based Fujitsu T4220 notebook the CPU frequency is permanently stuck at 800MHz (actual max is 2GHz) no matter what the load. This occurs no matter which governor is selected (userspace, ondemand, performance etc..).

On resume from suspend to ram, the frequency fluctuates between 800MHz and 1.6GHz for approx. a minute, and then goes back to being stuck at 800MHz.

Version-Release number of selected component (if applicable):
kernel-2.6.24-0.42.rc3.git1.fc9

How reproducible:
Always

Steps to Reproduce:
1. boot into fedora
2. check /cat/proc/cpuinfo ( will be 800MHz )
3. run something cpu intensive
3. check cpuinfo (still stuck at 800MHz)

Actual Results:
The CPU frequency doesn't change

Expected Results:
The frequency should increase to max if needed and go back to min when not.
