I've piggybacked on your debug patch and added some extra stuff to see if the 
__setup_vector_irq
is responsible for setting the new per_cpu. Those printk's _might_ not work as
all of that is being run on a secondary CPU that is being initialized..?

For the IO APIC programming I added a printk/debug_stack by the ioapic_write
to see who and when sets those pins on the IOAPIC to 3.
I had to modify the patch slightly to get the kernel not to panic, but it did mostly work after that. The results are attached.
