I really hope someone will commit this before 7.0 release, or it will 
never be part of RELENG_7_0
and not everyone want to track RELENG_7.

While still here any idea how to make powerd to not lower cpufreq under 
let's say 1000HZ?
I want to manually set the allowed minimum, because my laptop is lagging 
too much under certain speeds.

P.S. Nate Lawson & Bruno Ducrot CCed. They are pointed as tech contacts 
for powerd on the pages that I found :)
