It's been more or less implemented twice already, once for mga and again for r200, albeit before the days of HDMI. Patches are around on mailing-list archives [1,2] if you're interested. 1. http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg06185.html 2. http://permalink.gmane.org/gmane.comp.video.dri.devel/12790 -- Thanks, Donnie Donnie Berkholz Sr. Developer, Gentoo Linux Blog: http://dberkholz.com
