Bug#373947: powernow-k8: scaling cpu frequency not working with xen
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
I have here a similar problem here. powernow-k8 is working fine, if I'm
not using the xen-system.
With the xen system I get the following error messages and I can not
control the frequency:

Hopefully someone will find the problem (or it will be solved with
Kernel 2.6.19).
