I wouldn't myself classify it as a "workstation" cpu. And since it's a core2 chip it shouldn't have HT. It should be a true dual core chip.
As far as I know it's just a standard laptop cpu. Intel made a lot of different models with varying amounts of cache for a while for no apparent reason.
They may have picked that one since it's a 35w chip and the other series with lesser cache may have been 45w. And a big selling point for MacBooks has always been their battery life and they can get more life if they used a lower wattage cpu.
Or they could have just picked it just to be using the latest tech out there since they hit one of their refresh times or something.
