I guess I didn't specify this. This is for AMD processors only, specifically those with powernow. The cpuspeed *doesn't* have a kernel module, but the new 2.6.18-128 does have a new kernel module specifically called powernow-k8. This cpuspeed needs to get pushed out with the last kernel errata that we pushed out. But I want to make sure that it actually fixes the problem that people are having before I push it out.
