What errors do you see in /var/log/messages?
Maybe the binary akmod is not being created on boot?

Try booting without the "rghb quiet" part of the kernel boot line to see 
all the progress reports that happen during the boot process.

Do an "rpm -q -a |grep nvidia", you should see "kmod-nvidia" packages 
for all kernels you want to boot. If there is one missing for the kernel 
you want to boot you want to see why the build failed, I think there 
will be messages in the logs.
