I set machdep.lapic_allclocks to 1 at statup - top works now!! I can see
both processors with top -P, btw, everything looks fine, although I get core
dump for xfce4-taskmanager and can't test it (it's probably related to
something else).

I started powerd - it scales the frequencies correctly now.

This seems to be the solution, is this a bug should I report or leave things
like this?

Thanks a lot!
