CPU frequency scaling
CPU - A110 Wiki

modprobe e_powersaver
----------------------------------------------------------------
CPU frequency scaling with Linux >= 2.6.25
As the CPU has the est feature flag, it supports CPU frequency scaling using the e_powersaver kernel module.
The latest 2.6.25 mainline kernel already contains the e_powersaver module which allows CPU frequency scaling on the A110.

CPU frequency scaling with Linux <= 2.6.24
There's a backport for older kernels supplied by Christian Rothländer. It's working with the Ubuntu kernel delivered with the first batch of the A110s.
