Our PCI expert is Stefan Esser <se@freebsd.org>. He and Wolfgang wrote the
generic PCI support that appears in FreeBSD. I should have mentioned that
earlier - sorry about that. Please do contact him and provide the relevant
info (hardware config, and the dmesg output - especially the results of the
above printf).
