Well, I guess it's because sparc64 machines have DMA coherent memory
(i.e. bus-snoop support) so they don't require bus_dmamap_sync(9)
calls so strictly.

On the other hand, if a driver works on sgimips, it will also work
on most other ports (except ones which don't have BUS_DMA_COHERENT
support like hppa), I guess.
