We certainly should consider ditching SSE2 where SSSE3 is available now or in 
the near future. But in this particular case, James seems to be converting 
MMX(EXT) code into SSE2 code, more so that introducing pure new SSE2 code.

It took almost forever to agree to get rid of MMX. I would like to go ahead 
with that, and I like to think that many other people too. So can we at least 
tolerate porting MMX to SSE2 until we have gotten rid of MMX for good?
