I wish BUS_DMA_NOCACHE has real meaning (like what NetBSD did) since
uncached DMA is pretty much guarantee to make the driver works on
broken i386/amd86 hardwares.

Should we just narrow this down to i386/amd64 , or give
BUS_DMA_NOCACHE a real meaning as part of bus_dmamem_alloc() ?

I'm open for suggestion.
