  Log:
  SMP Natoma motherboards cannot know if you are booting a UP or SMP OS.  This
  mod makes sure that the Natoma chipset is set into the correct mode.  In
  the case of my P6DNF, when booting a UP kernel, I see a substantial improvement
  in the latency of certain operations.   It appears that the cache hit
  latency is curiously improved the most, per lat_mem_rd.
