Only the acpi_throttle driver has been MFCd so it only affects that 
driver in -stable.  We can continue testing the full set of drivers 
(including powernow) in -current with this setting.

Later on, I may consider just setting full speed in the acpi_throttle 
driver itself, but that has other issues (like preventing loading after 
boot).  If you're concerned, setting the values in /etc/rc.conf back to 
NONE gets you the previous behavior and this is better than hanging some 
slow systems.
