Log:
Add the Enhanced SpeedStep driver (EST). Currently, this driver only works
on the previous generation of Pentium-M processors (Banias). Support for
Dothan and later processors involves working with acpi_perf(4) to extract
information about supported states. This driver should work on MP systems
including HTT. It is experimental and may have a few bugs but has been
tested to not crash at least.
Thanks to Colin Percival for his initial work on this driver.
