Ubuntu on PowerBook

I formatted my hard drive today and repartitioned it with space for OSX and Ubuntu. Originally I planned on putting in a larger hard disk but cracking open an aluminium PowerBook is like tackling a lobster with a butter knife.
Ubuntu installed effortlessly on the machine with very little input from myself. I was even surprised to find my Apple bluetooth mouse works without having to do anything. Apparently the wireless will not work but that is because the wireless manufacturer uses a closed source driver.
