I think that Smallville is mixing up two different origins for Braniac here.  In post-Crisis continuity, Braniac first showed up as an alien spirit possessing the body of a carnival huckster known as Milton Fine.  On Superman: the Animated Series, Braniac was a super-computer that oversaw Krypton and, IIRC also was responsible for blowing Krypton up.
A third, non-Braniac related inspiration for this character may be the Eradicator from the comics.  The Eradicator is a Kryptonian artifact that embodied Kryptonian ideals, things like intellect, logic and the emotionless superiority of the Kryptonian race.  In the comics, it was always attempting to make Superman into a proper Kryptonian, first with persuasion and sometimes with force.  Eventually, after the "Death of Superman" it took on a human shape and became a superhero of sorts.
For Smallville, I think they're using the Milton Fine name and the Superman: TAS origin with Braniac as a computer/robot from Krypton along the lines of the T-1000.  From the dialogue, where Fine wants Kal-El to be a "proper" Kryptonian, it seems that they're also throwing a little bit of the Eradicator in there as well.  Currently Fine is posing as a "typical" Kryptonian to deceive Clark for his own purposes.
I'm really looking forward to where this leads.
