To me, Solaufein's initiative is equal to his eagerness to discover things for himself. Drizzt has some reputation in the world of the surfacers, and Solaufein knows it. Apart from that sort of admiration, he also feels the intimacy of the race.
And since we have talked it over, now, I want to ask why Solaufein's decision to ask Drizzt's assistance in the "Bodhi Show" has annoyed so many people! Is it because his action seems as if he is claiming the leadership of the group? or because no other NPC has ever done that before? or, because PC character is the god, and we should always consult the god before stepping forward?
Personally, I don't believe in any god, I didn't mind Solaufein's action in the least, and actually I enjoyed his dialogue with the Drizzt, and most of all the fact that it was him who introduced me to Drizzt, and not vice versa. It seemed more fair and realistic, and even more democratic.
There is only a single case in which I would had felt furious with Solaufein: if I was planning to fight Drizzt and his group, and have Drizzt's head for dinner. Well, I wasn't.
