Don't do that!

Using --force is a last resort for when all else fails and you know why 
and you understand what --force is going to do.  RPM doesn't refuse to 
install packages on a whim, it's trying to stop you from screwing things up.

For most packages you can use --oldpackage to tell it that you know the 
package you're tring to update to is older than the current package.

Kernels are different though.  You can parallel install serveral 
kernels, so you'd usuall use rpm -i oldkernel.rpm rather than rpm -U.

You can then use the new kernel by going into the grub menu on boot and 
selecting the older kernel from the list of available kernels.  At this 
stage you can rpm -e the newer kernel pacakage if you really want to get 
rid of it all together.
