Hi there Thomas ---

   Sorry, but to my understanding, anything ATI newer than Radeon 9200 
series (Rv280) does not have the native kernel level support for DRI/DRM 
under Xorg running on any BSD or linux.
There are proprietary (binary) drivers for Linux available from ATI 
which possibly support DRI or video acceleration features, but these 
drivers are generally reported/regarded as poor in quality and may be 
unstable under some linux distributions. YMMV.
Perhaps we should urge AMD (when they complete the takeover of ATI) to 
open the documentation to linux and BSD developers.

Best regards,
