Actually, NetBSD's PCI drivers are all machine-independent, and many of them
are already known work properly on big-endian and 64-bit systems (Atari,
Power Macintosh, Alpha).

The main issue w/ supporting the Ultra5 in NetBSD/sparc64 is the PCI
config, i/o, and mem space mapping, and the interrupt glue.

These amount to a SMOP, really.
