  Are you sure about this?  I was pretty sure this is being used as the
minimum address of the memory to allocate.  Starting at 0xffffffff doesn't
leave a whole lot of space to allocate from :-)

  Most other ports set minaddr to the address of the buffer memory
allocation.  The macppc port sets it to 0, and both the alpha and pmax
don't initialize it.  Hmm... interesting - the old pica machdep.c does
initialize it.  I would say the alpha and pmax are incorrect.
