Compiling a new kernel isn't a one way trip.
Since you can boot multiple kernel images it's pretty easy to just revert back to what was working.

Just download the source code for whatever version you need and compile it yourself. This isn't as painful as it sounds.
Yes, it really can be that painful and much moreso. Depending on how it's built, all sorts of random issues will creep up. Anything from not enough random data for ssh connections to function, to wtmp failure for login records to application malfunction. We're not even talking about future upgrades breaking because they rely on a particular kernel rpm being installed (think iptables) or the complete lack of upgrade path for security updates in the future. Rebuilding is a BAD idea.
It's much more sane to simply try to backport the module.
You're welcome to rebuild your own kernel all you want. However it's not 'recommended' advice. If it breaks, you get to keep all the pieces.
