Log:
Expand the hack to mask the atpics if 'device atpic' is not in the kernel
during boot up. Now we do a full reset of the 8259As and setup a simple
interrupt handler (we actually borrow the apic one that just does an
immediate iret) to handle any spurious interrupts triggered by either
chip. This should fix some folks that were getting a Trap 30 during bootup
of certain SMP AMD systems. This might get pushed into the 6.0 branch as
an errata. For now a suitable workaround is to add 'device atpic' to your
kernel config.

Hmm, we probably still need to reprogram the ATPIC on resume as well. I'm not
sure it's actually worth not just compiling the atpic code in on amd64.
Problems aside, what are the benefits to not having the atpic
unconditionally included on amd64?
