OK, it's R600 family.
After it arrived I found that support for RV620 didn't appear in
radeonhd until version 1.2 and the version in the gNewSense
repositories was too old.
A quick compile later and I had a fully functional video card. The 2D
performance is just fine and I find X to be very snappy. Even my 1080p
videos play well (they're using Theora and that codec admittedly isn't
very demanding in the first place.)
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.
