Not at this time, as nobody's ported the 3D driver patches to the r200
driver yet.

Instead of doing GLX_EXT_texture_from_pixmap by reading pixels from the
pixmap then passing them to glTex(Sub)Image, which results in the 3D
driver (re-)uploading the whole texture to video RAM regardless of how
many pixels actually changed (which is only usable forcing pixmaps into
system RAM with Option "XaaNoOffscreenPixmaps" / "FBTexPercent" "100",
effectively disabling 2D acceleration with a compositing manager), they
just point the 3D driver to the offscreen pixmap memory for direct
texturing with EXA (not possible for various reasons with XAA).

I think that should be fixed in xserver-xorg-video-ati 1:6.6.191-1 in
experimental.
