I already have a thread in the forun on that subject.

The hard part here is to find a distro that is working without flaws. From personnal experience, FC5, FC6 and Ubutu 6.10 all have problems of hardware recognition that make their use very annoying. I don't know about the free verison but Mandriva Discovery and Powerpack 2007 both work flawlessly. I haven't tried any other linux distro besides those I've mentioned.
However, once the right distro is found, I must say that the product is great. It's powerful and fast and it's cool to be able to activate the 3D effects.
