What version of FreeBSD are you using?

If you are running FreeBSD 5.4 or better:
You will probably want to set these variables in /etc/rc.conf:
performance_cx_lowest="HIGH"            # Online CPU idle state
performance_cpu_freq="NONE"             # Online CPU frequency
economy_cx_lowest="HIGH"                # Offline CPU idle state
economy_cpu_freq="NONE"                 # Offline CPU frequency

The one you want is:
economy_cpu_freq="NONE"
you will change it to something like:
economy_cpu_freq="HIGH"
