Comment 9 for bug 885204

Yes, this was introduced into oneiric. The current check might very well be too strong and err on the side of safety. You can of course still install the "nvidia-current" package manually. But even better would be if we would find a finer-grained condition when it's safe to offer the nvidia driver and when not.

I'm not quite sure how this works on your box, though. You use both the nvidia and intel card at the same time? That pretty much must mean that X.org running on the intel card does not have 3D acceleration?
