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. -- Nate
