PCMCIA is the obvious one I'm hitting here. The pcmcia core code as well
as being somewhat unreadable will happily hand out shared IRQs to
drivers that ask for an exclusive one leading to setup_irq errors and
non-working devices.

The main problem seems to be that the kernel will hand back the shared
PCI IRQ for a pcmcia port even when ExclusiveIRQ is requested. I've got
a patch here to clean this up a bit, but it changes the API to pass back
the fact the available IRQ is shared rather than force it, so may not be
a good candidate close to 2.6.17
