TurboBoost on 2.66GHz i7 systems
Apple's Mac Pro pages mention that the new Turbo Boost feature can increase the clock speed up to 3.33GHz for a 2.93GHz Core i7 system when working on a single threaded application. 
However, there is no mention of what type of clock speed boost to expect for other, lower speed Core i7 based systems.
Does anyone have pointers to data (from Apple or Intel) that indicates the top clock speed that can be achieved when Turbo Boost is enabled on a 2.66GHz Core i7 Mac Pro?

The boost is two multiplier levels (or just one multi, depending on thermals).
The normal multiplier on the 2.66GHz Nehalem is 20x133, or 2660MHz. So Turboboost would be a temporary boost of one or two cores to 22x133, or 2926MHz. Intel rounds this to 2.93GHz.
