Ah yes, there is an issue with that - when JEDEC specified the DDR2 specs, the SPD info on the RAM can only go up to 800 MHz, so in the official spec, there is no way for newer DIMMs to indicate that they are 1066 MHz modules.
This has been overcome to some extent - nVidia have created an unofficial extension to the SPD specification, called EPP. The problem is that manufacturer support for this is very patchy.
Almost all newer nForce chipsets boards support it, but amongst other manufacturers it is very hit or miss. Most likely on an Intel chipset board, you will have to set the RAM speed and the timings yourself.
I've found Corsair's forums quite useful - there's a lot of posts with tights timings for the Dominator RAM on most motherboards.
