   Log Message:
   For amd64, introduce a third free list distinct from the default free list
   for memory between 16M and 4G. On large memory machine, this avoids
   the 32bit-accessible memory being eaten by various kernel early allocation,
   causing 32bit bus_dma(9) memory allocation to fail at boot time.
   Tested on a system with 48GB RAM; based on netbsd-5 patch proposed on
   port-amd64 3 days ago.


i wonder if we should do this on i386 PAE as well?
