[ltp] CPU Throttling on R50p

[Winsley von Spee]

Hi

The Pentium M CPU's aren't able to scale to a lower freq than 600 MHz. The newer one (the one with the dothan core) are only able to scale down to 800 MHz. If something in Windows report a clock speed of 200 MHz it's wrong. Throttling doesn't change the cpu clock it just adds idle cycles to reduce the power consumption if the cpu is to hot. 

cat /proc/acpi/processor/CPU/throttling

Reports the available throttling states and which state is active.
