For those interested, all of the X.Org "DevRoom" talks are available online for video download from RadeonHD.org. Among the speakers were AMD's John Bridgman, Novell's Egbert Eich, Remi Cardona with Metisse, Daniel Stone, TG's Keith Whitwell for Gallium3D, Jerome Glisse, and Keith Packard...
It looks like all the videos are not of complete regarding lengths. At least the filesize does differ after downloading from the filesize listed on the website and they do stop before they are probably supposed to stop (that is eg bridgmans talk is really not complete, some mins are missing at the end).
