AFAIK an IRQ routing table entry gets ignored anyway if the appropriate device is not there

If it wasn't ignored, wouldn't you have to recompile your BIOS every time you added a PCI card to your computer or pulled one out? Wouldn't in that case boards only work if _all_ PCI connectors were in use.
A nonexisting NIC is no different than a PCI connector with nothing in it. From the system's point of view, it's just _nothing_ connected to the PCI bus.
