You can replace the key packages (kernel, glibc, openssl) by hand.  Boot a 
kernel that you don't want to upgrade, then "rpm -ivh --oldpackage 
--replacepkgs kernel-XXX.i686.rpm" and "rpm -Fvh --replacepkgs 
glibc-YYY.i686.rpm openssl-ZZZ.i686.rpm".  Then reboot to your new kernel 
and install the i686 version of your old kernel if you want.

The --oldpackage allows installing a package older than the latest.  The 
--replacepkgs allows replacement of a package with another of the same 
version.  You want to -ivh the kernel so you don't wipe out the one you 
are running.

As always, be careful, and make sure you have backups.  You might want to 
wait a little bit and see if anyone flames me to a crisp for suggesting 
this before you try it.
