cpu frequency scaling - you can either manually or automatically change the cpu clock speed, this works!
Very nicely, would be interesting to see how much cooler Dream and Sheeva run if anyone has a Temp sensor attached to a plug.

analyzing CPU 0:
driver: kw_cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 1000 us.
hardware limits: 400 MHz - 1.20 GHz
available frequency steps: 400 MHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 400 MHz and 1.20 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 400 MHz (asserted by call to hardware).
cpufreq stats: 400 MHz:72.48%, 1.20 GHz:27.52% (45)
