Sitsofe:
a manual installation requires a manual uninstallation.
"Manual installations" will always be there unless Ubuntu's dev decide to provide up-to-date proprietary drivers in Ubuntu's stable releases.
As regards the restricted-manager or update-manager, it wouldn't take much effort to replace the /etc/default/linux-restricted-modules-common with the one which comes by default with Ubuntu. Envy already does that (if you use the "uninstall" function)
