  SVN rev 216773 on 2010-12-28 20:11:54Z by jmallett
  
  When allocating memory from bootmem for the kernel to use, try to leave about
  2MB of memory in the bootmem allocator for the SDK to use internally at a later
  point.  It'd be nice if there were some functions we could call before
  allocating memory to let various facilities reserve some memory, but for now
  this seems sufficient.  Previously some unfortunate systems could give up all
  (or at least most) of their memory to the kernel from bootmem, and then
  allocating command queues for packet output and the like would fail later in
  the boot process (which in turn would lead to crashes even later.)
