+The driver now includes rc.nvidia-persistenced as an option.  While it can
+be run as root, it is more secure to run it as an unpriveleged user, so we
+run it as user nvidia.  Create the nvidia user and group with the following:
+
+    # groupadd -g 365 nvidia
+    # useradd -u 365 -g 365 -c "Nvidia" -d /dev/null -s /bin/false nvidia
+
+To activate the daemon, add the following to /etc/rc.d/local:
+
+# Start the nvidia-persistenced daemon:
+if  [ -x /etc/rc.d/rc.nvidia-persistenced ]; then
+    /etc/rc.d/rc.nvidia-persistenced start
+fi
+
+and then 'chmod +x /etc/rc.d/rc.nvidia-persistenced' to make it executable.

+Add the following to /etc/rc.d/rc.local_shutdown:
+
+# Stop the nvidia-persistenced daemon:
+if  [ -x /etc/rc.d/rc.nvidia-persistenced ]; then
+    /etc/rc.d/rc.nvidia-persistenced stop

+NOTE: This may not work on all systems.  If you encounter problems
