Yeah, I don't think they would be either. Give them the same Charisma as an elf. It wouldn't be any different than an elf bard.

Yeah, it's an interesting debate. I didn't play that much AD&D to remember giving a crap about charisma. Although, I do want to know about the mechanics factor of this. The imms had to have made a conscious decision not to let drow be bards and my guess its more for mechanics reasoning than anything else. I'd just love to know what those reasons were!
