  An aside on this...

  NetBSD supports the concept of different memory priorities,
  so it would be simple to make the system prefer the fast
  64MB over the slower 64MB. However the disk cache will use any
  otherwised unused pages so normally it will reach a steady state
  of complete memory anyway, which negates most of the gains in
  the above. NetBSD has  a unified buffer cache which excludes using
  the slower memory for the buffer cache. You could create a ramdisk
  on it and use it as the highest priority swap :)
