"Rumors and speculations have been flying around for months
about ATI/AMD opening up the source-code to their Linux display driver
or providing their GPU specifications to community developers. This for
the most part had started after Henri Richard's statement at the Red Hat
Summit earlier this year. Well, those rumors can finally be put to rest.
AMD will be providing NDA specifications, an open-source library, and
there is a new open-source graphics driver as a result. AMD will
continue producing a closed-source proprietary driver; however, they are
opening the source-code to a critical library with accompanying GPU
specifications for X.Org developers. To get the ball rolling, AMD is
also funding the development of a new open-source R500/600 driver."
