The consensus seems to be that creating a sys/dev/sbus would be a good
thing.

I don't think we'll do much more because:

	The PROM interfaces are different

	The supported buses are different (with a bit of overlap)
		(VME+SBUS+OBIO+MBUS vs UPA+SBUS+FHC+PCI)

	The trap models are completely different

	The architectures are really different (32-bit vs 64-bit)
