As noticed in a previous message:

Since are the least expensive machines that need most ASM optimization,
and being true that in this segment AMD is king, is my believe that ASM
code SHOULD be directed to it!

You can find the Optimization Manual at:
        http://www.amd.com/K6/k6docs/pdf/21924b.pdf

Notice that from this 70 page manual only 10 are relevant to crypto.
        (Pages 57 to 66)
