They aren't named sse3 in /proc/cpuinfo, they are 'pni' [1].
I think they aren't named sse3 because they also include
hyperthreading-specific instructions (not sure about this, I don't
have Intel CPUs with sse3 to show evidences of this).

PS: you know why Intel named its processor with the highest TDP ever,
'Prescott'? Just look here: http://en.wikipedia.org/wiki/James_Prescott_Joule ;-).
