I consider adding under/overclocking support to the community kernel (package kernel-flasher-maemo).
It should be safe to built a kernel that supports the entire 125MHz-1GHz range but only enables 250-600MHz by default.
Unfortunately the kernel boot parameter for the frequency range has been removed
in kernel 2.5.x http://www.mail-archive.com/bk-commi.../msg00015.html

The frequency range can be changed from user space by

Code:

echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 250000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Does anybody have a patch to add boot parameters for the frequency range?
