Only just played this myself - good game despite the cut content. Finished it twice now, good ending both times (I just can't bring myself to be evil - it makes me feel guilty) and assumed that everyone survived, except Bao-Dur's remote (and Kreia, obviously). I read on Wookiepedia that B-D was originally meant to die on the droid planet, but since that never made it out of the planning stages, I like to assume he and Atton were busy fixing the Hawk and getting it out of its predicament. If Kreia couldn't predict his future, it was because his mind was closed to her. And hopefully that means he'd appear in KotOR III, if it gets made, as he's one of the more interesting characters. (Hopefully along with Mandalore, who plain rocks).
Still, I do wonder what will happen now the Old Republic MMO is due. They are going to have to explain some of the past, even if that game is set 300 years after KotOR.
