IIRC, XRP is in the process of creating some, and I think they have a Pathfinderized .pdf version of their first eleven 1-on-1 Adventures.
Those are the only ones I know of.
I think it's going to be awfully hard to do adventures that are on par with Paizo's own. An author would have to have something that sets the adventure apart from what Paizo offers. A daunting challenge to say the least...
Nick Logue (Sinister) is releasing a high-level adventure sometime in the next few months. The names escapes me right now, but there's a thread here for it.

Edit: Ebon Shroud. It's going to include a Pathfinder conversion. So I guess it's not written exclusively for Pathfinder...
Someone, Dementia5 IIRC, is releasing an adventure called 'The Gift' at some point. Its a japanese ghost story setting and supposed to be the first of three.
Final Redoubt Press has a line of free adventure seeds. They're generic enough and look like they provide some info on different systems. It shouldn't be too hard to use with Pathfinder. I know it's not what you're looking for but hey they're free. Adventure Seed 1a: A Knife in the Dark - Final Redoubt Press | RPGNow.com
This is correct. Abbey is the first in our locale series which details one location that fits seamlessly into your Pathfinder or OGL setting. It's got crunch for players and adventure hooks (at the very least) for GMs.
