The pull request contains test cases demonstrating the problem. Buffer::HasInstance seems to fail. Tested on Node.js 0.8.2.

I haven't been able to figure out what's going wrong yet, so I'm putting this up here for now. Feel free to chime in with your thoughts.

Fix added, please review and pull! The problem was that the previous code for toBuffer returned undefined if Buffer.isBuffer returned true.
