The reason I ask is that I have the bus_alloc_resource() side of MSI 
(message signaled interrupts) working and wanted to connect it to the 
rest of the interrupt code via bus_setup_intr(). Do you have any 
short/long term recommendations? Do you want help on any of the above?

Alternatively, how badly would things break if I went around the system 
and wrote the IDT entries directly assuming there would be no overlap in 
the IRQ/MSI ranges?
