Log Message:
Driver for Intel Thermal Monitor (feature TM) On-Demand Clock
Modulation.

This works by changing the duty cycle of the clock modulation,
and saves power and helps to not increase the temperature by
software.

Adapted from OpenBSD/FreeBSD's p4tcc.

To enable it one must use "options INTEL_ONDEMAND_CLOCKMOD".

Tested by me in UP and SMP, ok'ed by Matthew R. Green.
