Listen - I went through the same thing with a Campagnolo Veloce BB. Do the following:
Take a Sawzall and cut the BB cups through (BEFORE you hit the BB shell steel, of course) parallel to the chainstays (where the least amount of threading would be damaged if you happen to nick them). Take a hammer and knock the BB cups to the center (see BB cup to the left) - they'll lose their strength and fall out.
