Well say the PCI buses timing gets hosed and the whole system seizes
up what do you intened to do at that point (that is a hardware
lockup)?  And what does that thing you do have to do with debuging a
kernel?  Just curious.

When you say "hardware" I start thinking jtag interfaces, or even more
interesting was this thing we would place every pin of the processor
through and then connect to the socket on the motherboard, but I think
I missing something.
