so in my quest to DTRT with BusDma, I changed the PCI code to
use bus_dmamap_load_raw as the SBus code was changed to do- after
all- if it is right for one, it must be right for another.

Tsk.

So- if we have an architecture that requires the use of bus_dmamap enad
bus_dmamap_load and so on, all architectures should be a bit more complete.
This would be more worthwhile pursuing than a dreamcast port or a __P hunt
(IMO).
