Same problem here on upgrade from 11.10. No options for proprietary drivers are displayed in Jockey. I'm running an old Nvidia GeForce FX Go5200 on Toshiba P20 laptop, probably about 8 years old as well. Unity 3D does not work as a result, and Unity 2D is unusable due to very slow and buggy graphics. Worked fine in 11.10 using the post-release updates version of Nvidia's drivers.
