I never used that closed source crap myself, but I just wanted to
mention that some Suse folks did some work on logind to do ACL
management for the nvidia device nodes even though these device nodes do
not appear in the Linux device model as used by udev (simply because the
device model is only available to free code). Not sure if this fixes the
whole problem, but there's at least a way to manage access to some
nvidia bits for unprivileged userspace.
