Thanks for investigating this!

I still wonder what exactly happens here (why does darwin panic?)

I'll add a 1000 MHz fallback, this is better than nothing.

CC'ing pearpc-devel

We already know that /proc/cpuinfo is non-optimal solution, especially
for processors with frequency scaling (i.e. for energy saving).
Unfortunately we haven't found a general solution for this yet.
