| 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.

| Reports the available throttling states and which state is active.

| well you can echo e.g. 200000 but it wont work, cause you can't alter

| | There _is_ a file in /sys/devices/system/cpu/cpu0/cpufreq called
| "scaling_min_freq" which is set to 600000 on my system.  You could try
