X server hangs X server not starting on reboot

Yesterday I was sucessful in getting the driver installed (169.12) and running many of the SDK samples that compiled. Today I had applied updates from Red Hat and now when the system boots the x-server complains and hangs. When trying to rerun one of the demo programs that ran fine yesterday I get the following error. I am running RHEL 5 64 bit. Any help interpreting this error and a recommendation to fix is appreciated.


Error: API mismatch: this NVIDIA driver component has version
169.12, but the NVIDIA kernel module’s version does not match.
Please make sure that the kernel module and all NVIDIA driver
components have the same version.
There is no device supporting CUDA.

Probably a Kernel-Update happened and now you have to generate a new kernel module… Run the installer again. (Be sure you have the kernel-sources installed)
