Hi Chris,

Try looking for powertop on Intel's site, and have a look for an
article about it on developerWorks (an IBM site, I think the base URL
is http://www.ibm.com/developerWorks).

This is a utility that lets you tune all the power management features
of newer Intel processors.

Ahh, found a link too. http://www.linuxpowertop.org/
