Well, the week has ended, and I - well, mostly my workmate who's on a 
conroe actually - wasn't able to test as extensively as I would have 
liked. The only instruction tested was pmaddubsw, and it worked.

I don't know how much nor what instructions we will be able to test, 
since it seems we'll test only instructions that we need for our work ( 
in addition to pmaddubsw, we will most probably use pabsw, pabsb, psignb 
, and we will perhaps find a use to phaddw and phsubw ).

However, I'll try to make a small test program for all the instructions 
this weekend - if I find some spare time.

Regards,

Mathieu
