Is it definitely a BIOS problem? If yes, we can close the bug of course.
I have a little bit of time to investigate the problem further:
(My knowledge is limited)
kory:/sys/bus/pci# for x in $(find . -name 'address' -print|sort); do echo -n
"$x "; cat $x; done
./slots/0-1/address 0000:3a:00
./slots/0-2/address 0000:3a:02
./slots/0-3/address 0000:5d:02
