It is easy to keep a backup kernel. I do it since the initial

1. Go to the boot directory****************************

#cd /boot

2. Find out the name of the running kernel*************

#uname -r

copy the number and pasted over the number in the example below.


3. make backup copy of your kernel and System.map******

#cp vmlinuz-2.6.22.13-0.3-default vmlinuz-2.6.22.13-0.3-bak
#cp System.map-2.6.22.13-0.3-default System.map-2.6.22.13-0.3-bak
#cp -r /lib/modules/2.6.22.13-0.3-default /lib/modules/2.6.22.13-0.3-bak


...


This is not enough, you need to copy also the entire /lib/modules/{kernel-version} tree, which is where the modules are kept.
