PCI device drivers must be prepared to share IRQs with other devices. If
it cannot, it is broken. You may never get it working.

ISE device drivers, on the otherhand, typically do not support such things.
What you should do is note the IRQs used by the ISA devices, then go into
the BIOS configuration and set those IRQs to "ISA Reserved" or some such.
How this is done depends on your BIOS.
