Folks, it is correct that this bug has recently re-appeared in the Raring beta kernel -- we're tracking this new regression at LP: #1163720. Please subscribe to that bug if this issue is affecting you in Ubuntu Raring. I'm working on a fix, and will post status there.
Note that the Sputnik Kernel PPA continues to provide a working solution for Precise and Quantal.
