Just out of curiosity, I clean installed my test machine (formerly working), and now seeing the same issues on that machine. And looking at /etc/modprobe.d/50-nvidia-default.conf, the NVreg_DeviceFileGID is still 483. Installed from NVIDIA's repository. I can promise you 100% I haven't manually edited this file.
