That's true, but I didn't just use WMI to try to get this information.
I also looked in the registry...although I forgot to mention that I
used the _winreg module to do so.

I did see that when I looked at Microsoft's Python scripts here:
http://www.microsoft.com/technet/scriptcenter/scripts/python/pyindex.mspx?mfr=true

MaxClockSpeed doesn't report the speed the same way MS does in the
System Properties, but I suppose I can work around that. Although this
will make AMD 3800+ procs look much slower (i.e. 2.4 Ghz in this
case).
