I re-played with this (single) option which showed no changes within
these pcictl-output. But: If I've activated all 3 PCI_*_FIXUP's I've
got the following diff:
$ diff -u pcictl.pci3.dump.-d.5.-f.0..without-pci-addr-fix

It seems to work under Linux (slackware 12.1 detects and runs some
cards (cardbus and pcmcia) I have fine), so there should be a way to
get it working under NetBSD, too. But how?
Would be some linux kernel output of detecting/attaching these cards
