Installing drivers from nvidia.com is not a supported way to install them and will not work like you said at the moment because of the extensive changes done to the packaging in lucid. 195.36.15 is available through the package manager as nvidia-current, and you can activate it through hardware drivers. Please remove the nvidia.com ones by running the installer with the --uninstall option before activating the Ubuntu packages.
