I *think* what has to happen is we need to push out the new cpuspeed 
that is in SL 5.3 to everyone

https://bugzilla.redhat.com/show_bug.cgi?id=459441
http://rhn.redhat.com/errata/RHEA-2009-0098.html

Basically, it looks like what happened was the powernow-k8 changes from 
being built into the kernel to a kernel module.  And the cpuspeed needed 
to be changed to understand this.

Can someone test this out and see if it works for them.
