Wrong dev.cpu.0.freq_levels values

[Pierre-Luc Drouin]

Hello,

I have noticed that FreeBSD gets the wrong CPU frequency levels for my 
Pentium M 2GHz. It used to work correctly with older versions of 
FreeBSD, but I noticed that this was not working properly when I 
installed 7.1 and this is still not working with -stable:

Mar 30 15:08:03 mdaemon kernel: CPU: Intel(R) Pentium(R) M processor 
2.00GHz (1995.14-MHz 686-class CPU)

dev.est.0.%desc: Enhanced SpeedStep Frequency Control
dev.est.0.freq_settings: 1500/-1 1200/-1 1000/-1 800/-1 600/-1

Is there a way to fix this?

Thank you!
