Please look at the output (top lines) of:
LIBGL_DEBUG=verbose glxinfo
In your xorg log you got direct rendering enabled.
You also more than likely need to upgrade your
ddx driver to 6.6.3 iirc this is the first version which
includes a fix for radeon 9800. For doing so:

git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati
cd xf86-video-ati
git checkout ati-6.6-branch
./configure --prefix=/usr
make && make install

You will need xorg dev package from your distribution.
