Don't they get their own directory that you can preserve in a copy? 
I've never had yum remove the running kernel, so never had to deal with 
it, but always assumed that you'd be able to boot the install disk in 
rescue mode, let it mount the filesystems, chroot, and then be able to 
tell yum to install the kernel version you need.  Shouldn't that work?
