Dumb question: How do I find out which is the right one for my p3 (whatever
a p3 is)? I am not sure where to look.

OK, I did this, and cpufreq-info returned:

cpufrequtils 003: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to cpufreq at lists.linux.org.uk, 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

I suspect this has to do with a missing "p3"...

Thanks, -b.
