Just read what the message says: it is not a kernel bug but simply your
BIOS is missing the _PSS objects on which powernow-k8 relies. I'm pretty
sure you had similar message in earlier kernels but it was a simple
warning then.

Is it possible to upgrade your BIOS? If you're lucky, it might've been
fixed :).
