I tested some more and found this.

It is XFree86 4.1.0 DRI (tdfx driver) related.
During my first run I used the 2.4.5-ac14 kernel DRM module.
Now I am running with the latest DRI trunk DRM module.
Both show the same symptoms.

After system and first Xserver start everything is fine.

Then after the first DRI (OpenGL/Mesa) app was running I get this:

SunWave1>l /dev/dri/card0
crw-rw---- 1 root video 226, 0 Jun 15 06:40 /dev/dri/card0

NO double /dev/dri entry. OK.

Who is to blame?
XFree? DRI? Kernel?
