I'm running FC4, and my processor speed was stuck at 798 MHz on my laptop. I added -C to the options passed to cpuspeed so that the processor runs at the full speed (2 GHz) when the power adapter is connected. Here's my /etc/cpuspeed.conf:
OPTS="$OPTS -n -i 10 -a /proc/acpi/ac_adapter/*/state -C -t /proc/acpi/thermal_zone/*/temperature 75"

Entering cpuspeed -h at the command-line shows several other options. Evidently, -D will keep the CPU at the fastest speed even with the power adapter disconnected. The options -m <speed> and -M <speed> set the minimum and maximum speed (in KHz) the CPU will run, but I have not tested this option.
