The problem is this: all cards not in slots 1-2 are assigned an IRQ of 1, which is obviously wrong. I'm not sure why slot 3 does not work, however, unless the code just thinks the PCI bridge *is* slot 3 (which it does appear to be that way). If no one is currently attempting to fix it, but someone would like to, here is all of the relevant info I can think of. Thanks in advance for any help.
