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).
