I started out with unichrome in 2003. I own a very comprehensive set of hardware today. I developed the fundamental concepts of modesetting today on unichrome. And without my work on unichrome, you would not even have a free r500 and up driver today (because then ATI would have gotten away with trying to kill radeonhd before the release), you would be stuck with fglrx and some spare-time attempt at a free driver that was struggling due to a lack of resources and a lack of information.
But really, what does any of this have to do with this topic?
