    sys/platform/pc32/i386 busdma_machdep.c 
  Log:
  - When creating dma map, allocate at least one bounce page even if the
    max size of the dma tag is less than one page.
  - alloc_bounce_pages() returns number of bounce pages that have been
    allocated, not error value.
  - Increase MAX_BPAGES to 1024 to cooperate with modern devices.
