That is coreect.
Just the titles, then a <CR> and prompt.

As I said this happened on both the newer kernels.

I downloaded the kernel rpm, then put it onto a usb stick.
No modules == no USB,
So I burned onto a cd/rw.
No modules == no CD.

I booted system_rescue_CD, mounted the F10 filesystem and the CD.
Copied over the rpm, and booted the older kernel.
Then used yum to remove the new kernel and then re-install it.

I am sure there is a better way, but this worked.
The problem was that you don't find out about the missing modules until you reboot.

So something gets set/reset, then during the next boot modules are not loaded, although the files are there.
