What symptoms do these problems create? PCI devices that conform to specs
can share ISA IRQs without problems. My main desktop machine had its
sound card sharing an IRQ with the NIC, my laptop has the USB chipset,
the sound card, and the PCMCIA controller on the same IRQ. None of that
ever caused any problems. The main thing to watch out for is that
having 2 devices with a lot of interrupt activity (SCSI cards, IDE RAID
cards, gigabit NICs) on the same ISA IRQ can reduce performance.

Just about all of the higher-end ATX boards I've seen allow you to do
that. But I really think your problems lie elsewhere. Fully describe the
hardware you're trying to use, fully describe the software config you're
using, then talk about the exact problems you're having.
