OK, it's R600 family.

Do you have XVideo working (you may check it using "xvinfo" command)? If your 
video playback is smooth, I suppose you have it. R600 have only textured Xv, 
therefore it needs accelerated OpenGL working also. Recompiling driver isn't 
enough for that, you'd need the latest Mesa and latest DRM (direct rendering 
manager) module for Radeons.

The latter contains blobs. It located either in Linux (starting from 2.6.32) 
or in Mesa/Xorg. 3D acceleration wouldn't work on R600 with deblobbed 
software. If you have accelerated 3D working (it could be checked seeing 
"glxinfo | grep OpenGL" output) then your system is using ATI blobs.
