Based on this document: download.intel.com/design/mobile/datashts/30218908.pdf
I added the 778, 773 and uncommented the 758 CPUs in the Enhanced SpeedStep
driver. These are some of the newer models of the Intel Pentium M CPUs. With
this change these CPUs can be throttled down using the syctl hw.setperf
mechanism. This should be tested by as many people as possible, especially if
you see a line like this in your dmesg:
cpu0: Enhanced SpeedStep 1600 MHz (1356 mV): unknown EST cpu, no changes possibl

Thanks,
