  SVN rev 216970 on 2011-01-04 19:10:54Z by yongari
  
  Partially revert change made in r212061. r212061 relied on
  bus_dma(9)'s capability which honors boundary restrictions of DMA
  tag for dynamic buffers. However it seems this does not work well
  and it triggered watchodg timeouts on controller that has the
  hardware bug. It's not clear whether there is still another
  hardware bug not mentioned in errata. This should be revisited
  since this change shall make use of bounce buffers which in turn
  reduces performance a lot on systems that have more than 4GB
  memory.
