From the thread at

http://mail-index.netbsd.org/port-macppc/2002/07/09/0002.html

it would appear that it is possible to manipulate the CPU into running at
full speed via Open Firmware. While the approach suggested is wired to
800MHz, and I believe also contains a typo, it is probably possible to
device a generic approach to this. The nvram script won't execute until
there is already a /cpus node, so it seems to me that a reboot to change
CPU speeds would not be necessary. It might take extra work to get the
Powerbook to actually go to sleep (and would be a nice feature), but at
least it'd run at full speed normally.
