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:

Is there a way to fix this?

Thank you!
