I have the same problem. Just added an old hdd and did a clean install. Hardware: Asus P5NE-SLi Motherboard Intel Q6600 Core2 Quad Processor 4GB DDR Ram 2x nvidia 8600 GT Video cards (linked by SLi cable)
Process was as follows: 1. Installed clean Ubuntu without problems 2. Logged in for first time without a problem 3. Installed the NVidia-Current drivers as provided by the Hardware Drivers panel in System --> Administration 4. Reboot and get a blank screen. At this point I restarted into my regular build and took a look at the log files. Kern.log and messages in /var/log show the following lines: May 2 13:22:01 eddy-testdesktop kernel: [ 266.445331] nvidia: module license 'NVIDIA' taints kernel.
