What's happened with PsyStar, is that they tried to do this _without_ the permission of Apple, and did so with software that was distributed under a restrictive commercial EULA. They didn't respect the Author's (Apple) intent regarding their software. That's the issue at hand (in my opinion) here.
I'm actually celebrating this judgment a bit - It highlights the value we get from Free Software. Nobody is going to come knocking on my door, sending lawyers, or dragging me into court because I'm running a business installing (modified) Linux on Computers. Indeed, the community will actually support me in my efforts to do so, http://www.linuxdriverproject.org.
