The driver requested an IRQ but didn't get it.

OK, I understand it's a non-transparent bridge.

I don't see any evidence that the problem is in MadWifi. In fact, I
tested MadWifi with a non-transparent bridge (RB14), and it worked fine.
If the driver cannot get an irq, it's correct for the driver to refuse
to support the device. The interrupts are managed by the kernel outside

check/post full dmesg; try to play with kernel boot params wrt
pci/apic/lapic/acpi - perhaps pci=routeirq.
