I am running an Asus A8N SLI with a 3800+ Dual core uname -r: 2.6.12-1-amd64-generic (ok, I know no smp....)If I try and insert the powernow-k8 module, it whines and doesn't insert it. It must be a bios related issue.... I did read about a newer version of the powernow-k8 module was in the pipeline in 2.6.13.
