That was fast.  JSONb's been updated.

Said he had no plans to convert from JSONb, but he'd accept a pull request.

Aeson's JSON type does't look much different than JSONb's type:
http://hackage.haskell.org/packages/archive/aeson/0.3.2.11/doc/html/Data-Aeson.html#g:1
It also offers ToJSON and FromJSON classes for conversion to other types.

That's a bit moot for the moment, though - it turns out JSONb works fine with attoparsec 0.9, despite the cabal file restrictions.
I left an issue about it up:

We can wait on the cabal file being updated, or just patch it ourselves in the meantime.

Ok, could you contact Michael Snoyman <michael@snoyman.com> the maintainer of
data-object-json could be upgraded to using JSONb? He is very active and might
help to resolve this issue.
