There is no problem when getting the frequency.
The only difference with linux is that instead
of displaying available frequencies (in the menu),
we display 25-50-75-100% - as we can only set
percents.
We unfortunately cannot get available levels, so
we don't know what is the max/min frequency
available for the processor, and it sometimes
causes problem with the speedcounter, which
doesn't know where to place the freq in the
counter.
PS: I forgot to mention that the freebsd support
is broken.
Here are patches again. This time it's really ok,
I also quickly modified the freebsd code.
