This is great news! Kudos!

Disabling atkbd/psm makes complete sense, everything is USB on the  
Intel-iMac. As for the APIC problem, it appears that we are detecting  
that the machine is a multiprocessor system, and failing to start the  
second CPU. Could the Core Duo require a different init sequence for  
its secondary cores than previous chips from Intel (Like the Pentium  
D and P4 w/HTT)?
