Wow, cool.  I don't think the new APIC code has been tested on a motherboard 
with a default config type yet.

Ok, can you possibly compile a debug kernel and get the faulting instruction 
(0x8:blahblah) address from this panic and use either addr2line or gdb's list 
command to find the associated file:line information?  Alternatively, if 
that's a PITA, I can give you a kernel to boot and ask you for the faulting 
instruction output to try and narrow it down.
