  Log:
  The DC driver asks for an alignment of PAGE_SIZE for data buffers, but also
  asks that each buffer be (2048 * 256) bytes long.  I suspect that alignment
  isn't a real requirement since busdma only recently started honoring it.  The
  size is also bogus.  Fix both of these and stop busdma from trying to
  exhaust the system memory pool with bounce pages.
