The rescue CD should contain tools to make recovery easier for all.

Anyway, I believe you want to enter Linux rescue. Next you want to 
chroot /mnt/sysimage.
You also want be sure that you have the /boot partition on your system 
mounted. This should have become detected by the rescue mode entry. 
However, since you do not have a kernel installed, you might need to 
mount the boot partition. Usually you will have a /mnt/sysimage for your 
root partition and another /mnt/sysimage/boot partition before you 
chroot to /mnt/sysimage.

List of tasks you need to do.
- Get into rescue mode and chroot to /mnt/sysimage.
- Ensure that you have your /boot partition mounted.
- Change to the RPMS directory or a directory which contains the kernel 
that you want to install.
- Install the desired kernel RPM with rpm -ivh
- check /etc/grub.conf to see if it contains information for the kernel.
- run grub-install /dev/<my-boot-drive>
- reboot

I hope this advise helps.
