When an onboard device and a PCI card conflict, you have to move the
card to another slot (or, better, to fix the driver(s)).

Has it ever been possible to change the IRQs of
onboard devices? I
thought it was hard wired.
the wiring into the IO-APIC is board-level, but the IO-APIC is
programmable and thus you can change the actual IRQ that the device
generates, in theory.
