Default CUDA driver disappeared after patch installation + kernel update

Unbelievable. I had a running CUDA installation on one of my machine
for about two days. Then I installed some patches and a new Linux kernel.
After rebooting, mfatkc didn't run. After digging around a bit, I tried
nvidia-smi -a and got:

FATAL: Module nvidia not found.
NVIDIA: failed to load the NVIDIA kernel module.
NVIDIA-SMI has failed because it couldn't communicate with NVIDIA driver. Make sure that latest NVIDIA driver is installed and running.

!!!! It was there before I installed the new kernel.

# dir /dev/nvidiactl
dir: cannot access /dev/nvidiactl: No such file or directory

I assume I need to reinstall CUDA. Has anyone else experienced this?
