It seems my machine is still locking up so I re-enabled ACPI I
downloaded cpufreq-utils and running cpufreq-info got the following:

cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux at brodo.de, please.
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
analyzing CPU 1:
  no or unknown cpufreq driver is active on this CPU

It is a P4 so I would think frequency scaling should be enabled. Is it
because I'm using the stock FC6 kernel? Should I be compiling my own?
