Having same code in k7 > and k8 drivers does not sound right. That can be shared by the two drivers if that is needed, but I don't think that part going to the cpufreq frequency tables. But I espected that powernow k7 and k8 are different beasts enough? There is no rvo, irt etc. for example in powernow-k7. > Anyway, lets see what happens.

Yes, but I guess there are more though. Just that we don't get enough reports yet. -- Bruno Ducrot -- Which is worse: ignorance or apathy? -- Don't know. Don't care.
