maybe I can check, but not sure because apparently xserver-xorg-video-radeon from wheezy/jessie/sid not works for me on linux, so if works on kfreebsd I won't see any effect. I have Radeon HD 7730M, I think the current driver (1:6.14.4-8) not support my gpu. but your patch will enable 3D acceleration? I'm dying to make playable 0ad :D
