I'm not sure what you did to get it into that state. did you rpm -U instead of -i ? You have the modules from one kernel, and the kernel image from another, which has no chance of working. removing, and reinstalling the kernel with -i should fix such a problem, but hopefully you've moved on to one of the updates by now.
