But it leaves the question, "what does the warning want me > to do and how do I do it?" The warning is telling you that your BIOS does not properly support POWERNOW-K8. From what little I have read about it, the kernel will try a fallback method to give the same functionality. If it can not do that, then you may not get the power-saving and noise reduction benefits that you would if it were working. You may be able to get a BIOS update that fixes the problem, or you may have to live with the warning. It is also possible that a later kernel will be better able to handle this. (A proper fix would be a BIOS update that follows the standards properly, but who knows if that will happen.) Hopefully, someone with experience with this will explain things better...
