Triple boot Snow Leopard, Ubuntu 9.10 and Windows 7 on 13" Macbook Pro

I have a 13" Macbook Pro (5,5) running Snow Leopard that I would like to triple boot Snow Leopard, Windows 7, and Ubuntu 9.10 on. I am running an 80 GB Intel X-25M as my primary drive and I want to have the three operating systems installed via the optical drive. I plan to replace the optical drive with a 320 GB hard drive to use as a data drive for all of the operating systems.
