There is no such software on any distro. Your motherboard's BIOS decides
which PCI slots get which IRQs. In a few motherboards the BIOS lets one
select which IRQs get assigned to certain slots, but most don't. So with
most motherboards all one can do is move cards around to different slots
and then see what IRQ gets assigned. If your sound card and your
ethernet card are sharing an IRQ, that's because those PCI slots used
both have the same IRQ assignment. If you swap just those two cards
slot-for-slot they will end up with the same IRQ again. Try moving just
one of the cards to another slot. If all of your slots are full then
move multiple cards.

On some motherboards with some processors you can turn on Local APIC
support in your kernel config and get more IRQs to work with. Dual
processor motherboards, even if they have only one CPU installed, can do
this to get more IRQs. If you have dual CPUs you should already be
running a SMP kernel and you probably don't have IRQ assignment
problems. If you do, it's back to juggling cards.
