  Modified files:
    sys/i386/isa         npx.c 
  Log:
  Only use the i586-optimized copying and zeroing functions if they are
  actually faster (more than 20% faster for zeroing 1 MB at boot time).
  This fixes pessimized copying and zeroing on K6's and perhaps on other
  CPUs that are misclassified as i586's.
