interesting...the memory ranges are used by other devices yet the
request_resource() call in PCMCIA succeeds,,,and PCI resources shoudn't
be there in the first place then...
ok, it's in file arch/powerpc/platforms/powermac/feature.c...
i can't see any request_resource() calls in there...so CC'ing the PPC guys..
they can sure comment...
