I've purchased it on AP Malz as a bot laner (who I took w/ Revive+Garrison). It has better synergy with him than with most, since it acts as a way to increase Voidling damage w/o AD (and augments his already powerful pushes.)
That being said, Banner was designed for teamplay (anyone hear about the triple Promote strat one team took in the S2 world championships?) not Dominion's bot lane. It's a noob trap on pet champs who aren't going bot, and it certainly isn't an item you should rush willy-nilly. The only 2 champions who I actually see benefiting substantially from the passive without necessarily needing to go bot are Elise (as a later item, once she has enough spiderlings to make use of it) and...Heimerdinger (the only champ I could really see rushing Banner)...who already tends to see more use in bot than top.
I'm guessing that dedicated bot lane Zyra (and MAAAAAYBE Yorick, not sure) could get it as a third or second item, but other than that, no dice.
