Or, it could just simply be a coincidence. Last I heard, the Prescott design has a few optimizations for hyperthreading. With that in mind, it wouldn't be too far of a stretch to simply take the two existing ALUs in the older P4 design and tweak them to run better resulting in a die layout that screams "dual core" to most people.
Just a thought.

Actually prescott (and northwood 99% sure) have three ALUs, 2 simple, 1 complex.

Technically, a few more than that, but I was referring to the two double-pumped ALUs that handle the most common instructions and accidently left out that disctinction.
