Plus, the K6 can process MMX instructions at the same time as other
integer instructions. On the other hand, it can only process one MMX
instruction at a time while Intel can do two at a time.

All of which is a moot point here, unless someone is close to putting out
an MMX-optimised deschal6.exe (deschalx.exe, perhaps?). I saw on the home
web page a request for access to such a processor but it would be nice to
know where they stand on that and how fast it is.
