Well, there is not only the IDE driver; the USB driver does it as well:

In the 2.4.25, from the "drivers/usb/host/usb-ohci.c", in the 'ohci_pci_probe' function:

And in the 2.6.7, from "drivers/usb/core/hcd-pci.c", in the 'usb_hcd_pci_probe' function:

if (!dev->irq) {
	err("found OHCI device with no IRQ assigned. check BIOS settings!");
	pci_disable_device (dev);
	return -ENODEV;
}

There are probably other drivers that have the wrong assumption that IRQ 0
is an unassigned IRQ.

They are broken. They need fixing. Please don't just work around their
brokenness -- send patches to the driver maintainer.

Yes, please do :)

thanks,
