Yes, I get various PCI: Enabling ... messages.

Maybe it would be good to post your dmesg to the list, you might also
try adding debug and/or verbose to your boot arguments to see if you
get more messages.

IIRC, BootX has some logs you can turn on, maybe they would shed some
light also. Maybe some MacOS code is running that won't give the video
card up.
