Dave,
What is the drm control device nodes really used for?
On my fc14 system it seems like it has world rw privileges, and full access to all modesetting ioctls. Is that the intention?
No, and I just realised we packaged a broken udev rule.
It should be root only, oops.
Its intention is for setting up multi-seat and gpgpu access to the drm.
change /etc/udev/rules.d/91-modeset.rules to be 0600.
I've filed updates to Fedora to fix this, no other distro should be using or caring about these device nodes yet, since we never really got GPGPU going yet.
