hmm I just got something wrong :
 I was not really sure (I know that now) where dri/drm modules modules
came from ...
there are kernel modules from my 2.4.0test6 kernel called "drm.o"
"mga.o" "mga_drv.o" in /lib/modules.../drm/ and in the xserver-xfreee86
package there are
some files called "/usr/X11R6/lib/modules/dri/mga_dri.so" and
So I got confused what object file is what.
I thought that it is redundant (mga_drv.o) .
After all dri didnt work for me although I have a
/proc/dri/0/  directory ...
X said "(EE) MGA(0): [drm] MGADRIScreenInit failed (DRM version = 1.0.0,
expected 2.0.x)
.  Disabling DRI." so I thought that there was a modules version
mismatch ...
I read the DRI Howto which said :"3D hardware acceleration requires a
DRI kernel module that's specific to your graphics hardware. 

The DRI kernel module version must exactly match your running kernel
version. Since there are so many versions of the kernel, it's difficult
to provide precompiled kernel
modules. "

Maybe I dont need to enable drm in my kernel because X brings its own
modules, but then they must match my kernel version, so I thought a
seperate DRI package would be great.

maybe I get it working, then I know that I was totally wrong and the
current way of packing X is great. (Of course otherwise it is also great

Yes thanks a lot.

I was thinking of a config tool to create the X make files (*.cf *.def
to be able to get a running ( mine isn't running yet ) and optimised X
server and dri modules as well as mesa librarys.

I am sorry if I got some of these things mixed up.
thanks for the competent and quick answer.
