At least I am. Resolution (UNLESS IT CHANGES FIELD OF VIEW!) doesn't have ANYTHING to do with tesselation. The units which handle tesselation do not handle per-pixel operations, as far as I know, so there is no extra work for those units. The work remains the same regardless of the resolution.
However, obviously even with tesselation, the resolution has impact on the framerate, because there is a limit how many operations the ROPs can do, and how many operations the TMUs can do. With bigger resolution they need to do more. And they also need a bigger share of the memory bandwidth, too.
