 Hi, Hanns.
 I found this PR from search engine (google).
 This PR is slightly old, though, i send this e-mail.
 Phenom II or so will not have est(speed step) it's for intel cpu, and
 Instead amd cpu will have powernow or hwpstate, i think.
 Please send the results of followings.
 1) sysctl -a | grep freq (will show powernow or hwpstate related things)
 2) powerd -v ( make powerd run foreground and with verbose mode )
 and i hope powerd is doing its job.
 Thanks in advance.
