OK, to the meat of the story. AMD is making the commitment to do two major things:
* To develop of a fully functional 2D and 3D driver that supports all of their newer radeon chipsets. This will be done in full collaboration with the open source community and will have the direct participation of hackers from companies like Red Hat and Novell.
* To release documentation that anyone can use to build and support drivers for their chips.
