multiprocessing arrangements (hence the MP.) Athlon XP is it's single
processor cousin. It appears these are in fact the same processor,
with the MP's having slightly more testing involved to be SMP
certified or some such. The Duron 1Ghz and above are also Palomino
based, but lack some of the features of the XP and MP, IIRC.

Couldn't a test be done on the Features information of the processor
to determine the best optimizations? Or would that break
cross-compiliation of optimized code?
