[cpufreq] speedstep support via GSI driver

[Bruno Ducrot]

Hi Nate, Jon,

The smist driver (speedstep support for older kind of Intel's speedstep)
is (maybe?) ready for inclusion.  I CC to -acpi in order to get more
feedback about this.
It was tested on current with success by Jon (but should work with
stable as well).

The driver is available at
http://www.poupinou.org/cpufreq/bsd/smist.tar.gz
or

Cheers,
