Anyone know if you can get look up and look down commands to work?

I'm trying to get my PS3 controller to work with a bunch of different valve games, and it all works great, apart from one thing. Looking up and down. This is a bit of a problem, really. I've heard that valve disabled it because people were writing anti-recoil scripts for the games, but I'd still like to try to get it to work.

Any help?

Thanks
