As BlueEagle said Boeing strongly recommends that the airplane nose must be "flown" into the runway, not only for the reason that he has mention, being the possibility of a hard nose landing gear contact with the runway, five years ago there was a safety seminar conduct at our airline and the Boeing guys shows us a couple of pictures of nose landing gear struck into the fusale and a 767 with the whole fuselage bended behind the nose landing gear.
The reason being that as you lose speed rapidly the elevator not have enough authority to reduce the rate at which the nose goes down, with that kind of results.
