I just found out sth which makes my CPU work with F17 on 1.83 Ghz:
Add the following to a startupscript:
echo 1833000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1833000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
it seems that you have to set the governer again after setting the
scaling_max_freq.
cpufreq-info output is:
[EMAIL PROTECTED]:/usr/src/linux-2.6.19.1# cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to [EMAIL PROTECTED], please.
analyzing CPU 0:
driver: centrino
CPUs which need to switch frequency at the same time: 0
hardware limits: 1000 MHz - 1.83 GHz
available frequency steps: 1.83 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: userspace, powersave, ondemand, conservative,
performance
current policy: frequency should be within 1000 MHz and 1.83 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.83 GHz (asserted by call to hardware).
analyzing CPU 1:
driver: centrino
CPUs which need to switch frequency at the same time: 1
hardware limits: 1000 MHz - 1.83 GHz
available frequency steps: 1.83 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: userspace, powersave, ondemand, conservative,
performance
current policy: frequency should be within 1000 MHz and 1.83 GHz.

sincerly,
