For PCI and AGP devices the IRQs are typically set by the BIOS/firmware. 
  On many "white-box" (aka non-name brand) systems you can control which 
IRQ gets assigned to which slot in the BIOS.

You can find what's using what IRQ with 'cat /proc/interrupts' and 'cat 
/proc/pci' and '/sbin/lspci -v'.  You may need to install the 'pciutils' 
package for the last one to work.
