The list of supported ATI cards is posted on the Xorg site and I know that all currently marketed desktop/netbook cards and GPUs from ATI are supported for 2D functionality.
This is in the man notes of Xorg but I'll add the old notes: http://ftp.x.org/pub/X11R7.0/doc/html/radeon.4.html More current: http://www.x.org/wiki/radeon http://www.x.org/wiki/radeonhd You can do this for testing: Run a 1080p test video stream through Mplayer or VLC at a 1920x1080x60 resolution using EXA acceleration and Xv enabled. No artifacts or dropped frames should be visible. Use an ATI GPU >= R500 series. Pull the latest ati/radeon drivers from Xorg git and contact the Xorg/ATI developers for any assistance besides Sun's kernel ATI/Intel DRM driver team mentioned in the other thread (or whomever is currently doing the work). ~ Ken -- This message posted from opensolaris.org
