Try the "PCI Options" section of your computer's BIOS.

But this is not an option for many machines like my notebook for
example. There I have the problem that the PCI IRQs seem to be allocated
by random. Sometimes the USB controller shares the interrupt with the
soundcard which saves one IRQ for PCMCIA devices and sometimes seperate
IRQs are used.
It would be really nice if one could change that and accumulate devices
that _can_ share interrupts on one single IRQ.
