Maybe a couple of lines of dialogue here and there, but not really. There were no extra "scenes" that I could discern, at any rate. Others, please feel free to correct me on this if I'm wrong.
More than a few extra lines of dialogue - for example, the novelization "explained" that Harrison really beamed up to a ship in orbit with the portable device, then went to Qo'noS. I noticed a number of other expansions as well, that seemed to be "made for the page" rather than cut material.
But yes, I don't remember there being any extra scenes.
Ah, right! I forgot about that one. Although it still indicated that he used transwarp beaming from the ship, but that it used all of the power of that ship if I recall correctly. That made more sense to me than what we saw in the film.
