Because it is only valid for the particular motherboard used in the FSC
P200/C200 and would most likely break SMP for other motherboards.  A
"valid" patch would detect the problem (the hang) and the hack the APIC
I/O ints table only in this case.

This is my understanding of the issue anyway.

I don't know enough about the FreeBSD kernel yet to do a proper patch.
