I wanted to route the PCI IRQs to those lines (and have eight links 
instead of four).  Now I don't think it's worthwhile, as every guest 
that is interesting from a performance point of view has MSI support.

So I think we should just leave these lines as is, terminated with a 
4.7K resistor to avoid picking up noise.
