Comment 5 for bug 464591

For me, the problem was as simple as booting with a different .31 kernel. For whatever reason, 2.16.31-14-386 was installed as the default kernel, causing the problem as described above (error message: "(EE) Failed to load module "nvidia" (module-specific error, 0), (EE) No drivers available."). 2.6.31-14-generic was installed as an alternative kernel, which booted just fine.
