Arr. Yes, ofcourse. Okay... that ain't working:

It doesn't. With the test negated it triggers for all PCI resources (and

ofcourse my soundcard driver fails again).
If the simple res->start == 0/SOME_ARCH_DEFINE definitely won't do and

the issue with Bjorn's approach is the bus hammering the solution might

be to set a per resource flag in pci_dev at parse time?
(that's PCI though and I can't really be here at the moment so over to

someone else).
