cpufreq/powerd workaround?

[Ali Mashtizadeh]

Hey Everyone

On both my X2 and my Turion single core cpufreq has been a problem. It seems
it is acpi_throttle, part of cpufreq, that seems to be the real issue. So I
added this line to my /boot/loader.conf file and everything is fine now.
I've run 7-CURRENT and 6-STABLE.

hint.acpi_throttle.0.disabled="1"

(It looks like you have acpi_throttle enabled since you have so many
frequencies listed)
