There is a cpufreq daemon that does the same thing, on my P4 3.0 I had
the frequency drop from 3000MHz to 1250MHz and I thought that I was
saving electricity. I plugged the computer into a Kill-A-Watt
electricity meter. At idle the box was using 91Watts, it did not matter
if the CPU was at 3000 or 1250 same 91 W, but the box was slower at 1250
then 3000. Under load it would use 115 W. I did not measure the
temperature. I gave up on the speed step.
