I would not be surprised to find that the RC5 optimization are an
algorithmic one. If they use floating point math in their caclulations
then Cyrix suffers badly, if they use solely integer then the Cyrix chips
fly, but the intel chips can hurt a bit.

AFAIk the kernely doesn't do much floating point so this doesn't really
