Good advice. This whole IRQ / slot sharing thing is a pain. There should
be a law that says if there is a card slot, it gets a dedicated IRQ. Same
for onboard devices. Wouldn't that be slick, no matter where you stuck a
card, there wouldn't be any IRQ sharing problems?

So the chip set dudes need to fix it on their end and the OS dudes need to
fix it on their end so the mobo dudes can make motherboards that are really
easy to setup and use.

You've got it already. Just use the slots that don't share, and set
them up as Legacy Devices in BIOS. Trouble is, most people want more
devices in their computers than that approach allows :-)
