You can check the device tree in OpenBIOS by using show-devs to see how many CPUs are
present, and confirm that the properties are set correctly.
The reason that SMP hasn't been enabled for the Mac machines is mainly because no-one
has been inclined to work on it yet ;)

Try rebuilding OpenBIOS with DEBUG_CIF enabled in libopenbios/client.c which will
show the calls being used by the bootloader.

==================
I think this mean forth just jumps back to its interpreter instead of booting after enabling debug ?
and despite cpu number printed in banner it still only creates one cpu node?
