Ah! I cranked up xbmc in windowed mode, which likes it's share of CPU,
and got this:

wayward4now at iam:~$ cpufreq-info
cpufrequtils 006: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq at vger.kernel.org, please.
analyzing CPU 0:
  driver: powernow-k8
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 109 us.
  hardware limits: 1000 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 1000 MHz
  available cpufreq governors: conservative, ondemand, userspace,
powersave, performance
  current policy: frequency should be within 1000 MHz and 2.00 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.00 GHz.
  cpufreq stats: 2.00 GHz:23.18%, 1000 MHz:76.82%  (888)

So, it does work, I just needed to really task the CPU for the system to
crank up. 

BTW, xbmc is one helluva multimedia application. Find "toxic-friend.mod"
and crank up xbmc with /settings/music/playback set to Project M, you'll
have one snazzy light show and bewilder your kids!. 

Use the tab key to get rid of the menu and use the \ key to switch
between windowed and full screen mode. Way cool, especially for us OLD
hipsters who still like to rock. 

For the latest beta just head over here:
http://wiki.xbmc.org/index.php?title=Installing_XBMC_for_Linux
...and follow the Ubuntu instructions. The version in the repo just
started seg faulting on me, so I just enabled the ppa for xbmc. :) Ric
