Ugh, this was the problem:

# lsof /dev/dri/card0
COMMAND   PID   USER   FD   TYPE DEVICE SIZE  NODE NAME
3ddeskd 19721 stefan  mem    CHR  226,0      18084 /dev/dri/card0
3ddeskd 19721 stefan    5u   CHR  226,0      18084 /dev/dri/card0

After killing 3ddeskd (from package 3ddesktop), Xorg was able to use the DRI 
again. When I start 3ddeskd after Xorg, I can use both together. But when 
3ddeskd is already running, Xorg can't enable its DRI support.

As a workaround I added

  killall 3ddeskd

into
  
  /etc/kde3/kdm/Xreset

which seems to work.

I think theses packages should work flawlessy together out of the box and so 
this is still bug report-worthy. But I'm not sure which package needs to be 
fixed and whether this bug report should be moved to another package.

Greetings, Stefan!
