There is really a but in the resource allocation. Please take a look at
the attached log files. The ATI card has PCI IO resource so there
is no bogus resource in the northbridge. As the Nvidia card it does
not have PCI IO resource so we got the 20000 to 1ffff thing.

I don't think so.

Those function are not actually used. You can try to mark them.
