You're headed for trouble with this change. According to bus_dma(9),
memory allocated with bus_dmamem_alloc() should be loaded with
bus_dmamap_load_raw().

The sparc and sparc64 implementations depend on this, since both the
`alignment' and `boundary' argument to bus_dmamem_alloc() cannot be
dealt with until actual DMA resources are allocated. Those values
are saved in the segments returned for later use in bus_dmamap_load_raw().
