I can confirm I have this exact same problem. I have an Nvidia 9800GT 512MB. When I install the proprietary driver, I restart. Before it gets to the Ubuntu loading screen the screen goes completely black!
I have tried it at least 5 times and its still the same result. Getting that Nvidia driver working for me lately has become a real sore spot of Ubuntu.
