Hi,

when I filed the report I was using radeon ums, but now I have radeon kms with 
libdrm&mesa&xorg packages installed from ubuntu lucid:

Now when I rename r300_dri.so to something else, then the Xorg.0.log says:
(EE) AIGLX error: dlopen of /usr/lib/dri/r300_dri.so failed 
(/usr/lib/dri/r300_d
ri.so: cannot open shared object file: No such file or directory)
(EE) AIGLX: reverting to software rendering
(II) AIGLX: Screen 0 is not DRI capable
(II) AIGLX: Loaded and initialized /usr/lib/dri/swrast_dri.so
(II) GLX: Initialized DRISWRAST GL provider for screen 0

And compiz says in .xsession-errors:
/usr/bin/compiz.real (core) - Fatal: GLX_EXT_texture_from_pixmap is missing
/usr/bin/compiz.real (core) - Error: Failed to manage screen: 0
/usr/bin/compiz.real (core) - Fatal: No manageable screens found on display :0

And the fallback window manager appears (kwin without compisiting). I don't 
know if this is relevant for debian.
