Thanks, I checked all these infos, but they do not seem to fit for mysituation (see below).

So, do I have - maybe - to delete something from MESA ? I work mostlywith apt-get and I cannot remove MESA without also removing all thatdepends on :-(the ati module can be loaded into the kernel, XFree86 does not reportproblems and still - no hardware acceleration!maybe something with mtrr ? (How can I find out/ fix it?) -> somethingin menu.lst (-> grub?)

Something probably went wrong, and you are using software rendering.fglrxinfo and glxinfo probably mentions "Mesa GLX indirect", no Direct
Rendering. This means slooow 3D ;-)

You should check out what the drivers print in /var/log/XFree86.0.log
and see where it fails. It will probably be a lot more helpful than
dmesg. Look for lines starting with (EE) or (WW) (Errors and Warnings)

thanks for further hints. I do not understand it as fglrx can be built,loaded into the kernel, but no acceleration,
