Bug Description
gutsy - xserver-xorg-core - wrong device permissions on /dev/dri/card0 (crw-rw----) instead of (crw-rw-rw-)
When debugging my video driver on gutsy to try enabling direct rendering I found the following:
libGL: OpenDriver: trying /usr/lib/
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (Permission denied)
drmOpenDevice: open result is -1, (Permission denied)
drmOpenDevice: Open failed
The permission should look like this:
ls -hal /dev/dri/card0
crw-rw-rw- 1 root root 226, 0 2007-08-28 09:54 /dev/dri/card0
but actually are crw-rw----
Which package is responsible for setting the permissions for the card0 device?

executing glxinfo and glxgears with superuser rights provides access to unichrome_dri.so and gives information that direct rendering is enabled. Is the permission a bug or a new security feature?
