  Log:
  Attempt to fix Symbios driver on amd64. The private memory allocation
  function provided by the driver limits allocations to the page size,
  i.e. 4KB on i385 and 8KB on typical 64 bit processors. Since amd64
  has 64 bit pointers, but only 4KB pages, an array of pointers that
  just fits into one page on all the other processors, does require
  2 pages on amd64.
  
  In order to make this driver useful on amd64, the allocation unit
  has been increased to 2 pages on amd64 and contigmalloc() is used
  instead of malloc(). All other processor types are unaffected by
  this change. This modification has only been compile-tested on
  amd64, yet, but should just work (FLW).
