Upgrade to 8.04 does not detect nvidia drivers

After upgrading to Hardy Heron 8.04, my nvidia drivers would not load. Restricted driver manager shows driver installed but not in use. Card is a GeForce 5200. I reinstalled the drivers to no avail. Here is copy of my xorg.conf file:

Anyone have any ideas?
