To answer my own question...... Needed to add cpufreq=dom0-kernel to my
Xen boot options, this fixed Powernow completely.

Subject: [Xen-users] Powernow Failure with Xen Kernel
Sorry to have so many questions but I seem to have quite a few mini
problems with my first Xen setup. My xen server works fine with Powernow
on the standard Kernel but with the Xen kernel it fails. Does anyone
know why? Details below.
With Standard Kernel
