We're going to install a flavor of Snow Leopard (10.6.3) and make some changes to kexts (like drivers for a Mac) to get everything working nice.
Through quite a bit of trial and error I was able to get it working nearly flawlessly, so I figured I would detail the exact steps it took. If your configuration is different, you're likely to get somewhat different results, but the process is basically the same.
I have also put together a video that takes you through these steps in about ten minutes. You might want to use both the video and the directions below as you work on your computer.
