Some BIOS's prefer to give only one interrupt to all PCI devices anyway.
My old Intel Somethingorother(Plato?) motherboard had to be tricked into
assigning my ethernet and SCSI two different IRQ's; the first time I booted
with both present there were several IRQ's available to the BIOS and it
still assigned them both the same.
