Subject: cpufreq: last commit for 2.6.29 break cpufreq performance module

Hello,

After this commit 6707fbb56c8fd3121e334291d170934bcaca2e7f, if i
change the governor of cpufreq to performance, my processor still
shows 800MHz instead of 2268.

dub:/sys/devices/system/cpu/cpu0/cpufreq# cat scaling_governor
ondemand

dub:/sys/devices/system/cpu/cpu0/cpufreq# cat cpuinfo_cur_freq
800000

dub:/sys/devices/system/cpu/cpu0/cpufreq# echo performance > scaling_governor
dub:/sys/devices/system/cpu/cpu0/cpufreq# cat scaling_governor
performance
dub:/sys/devices/system/cpu/cpu0/cpufreq# cat cpuinfo_cur_freq
2267000

But, /proc/cpuinfo shows 800MHz:

model name      : Intel(R) Core(TM)2 Duo CPU     P8400  @ 2.26GHz
stepping        : 6
cpu MHz         : 800.000

And i cannot remove the ondemand module:

dub:/sys/devices/system/cpu/cpu0/cpufreq# rmmod cpufreq_ondemand
ERROR: Module cpufreq_ondemand is in use

I can confirm that it's not on 2268MHz because glxgears runs below the expected.

No errors on dmesg too.
