Clayton,

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

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

4.  create initrd **************************************

#mkinitrd 

5. Check if new initrd was created:*********************

#ls
and look for initrd-2.6.22.13-0.3-bak

6. Backup  GRUB menu*************************************

#cp -r /boot/grub/menu.lst /boot/grub/menu.lst_bak

7. edit grub menu****************************************

# kwrite grub/menu.lst

8. Add new entry at the end of the file. You can copy the original entry
for SUSE LINUX 10.2 and do some changes;

title BACKUP openSUSE 10.3 - 2.6.22.13-0.3 
    root (hd0,0)
    kernel /vmlinuz-2.6.22.13-0.3-bak root=/dev/sda6 vga=0x346
resume=/dev/sda5 splash=silent showopts
    initrd /initrd-2.6.22.13-0.3-defaultbak

9. Test it***********************************************
