Subject: raid5 autoselecting a slower checksum function

This is 2.6.0-test2 on a Celeron 900:

raid5: measuring checksumming speed
   8regs     :  1640.000 MB/sec
   8regs_prefetch:  1316.000 MB/sec
   32regs    :   824.000 MB/sec
   32regs_prefetch:   788.000 MB/sec
   pIII_sse  :  1744.000 MB/sec
   pII_mmx   :  2244.000 MB/sec
   p5_mmx    :  2400.000 MB/sec
raid5: using function: pIII_sse (1744.000 MB/sec)

Why doesn't it select p5_mmx if it is 37% faster than pIII_sse?
