where pci=noacpi helped. IMO not worth an automated detection.
Especially for those old machines..., people know which param to use, you
will produce more grief than any good.

There were several acpipnp problems recently, but this is another topic
and that needs fixing anyway, Bjorn is doing a real good job here.

Hmm... Maybe what's necessary it to detect IRQ misrouting and turn on
irqpoll on the specific IRQ (or IRQ handler), which would help 'nobody
cared' cases too.

But you risk that things never get fixed correctly.
At least yell loudly at the user that things must get fixed.
IMO the a message (you already see appearing?) at the right place:
try irqpoll, try xyz param is enough.

The current behavior is not that bad and not that much machines
(at least new machines) are affected, but as said I am not
deeply involved in PCI/IRQ things.
