I don't really have an answer to your question, but there is a trick which
(had you used it) you would not now be in this situation. 

When you put your new kernel into /boot as vmlinuz* change your old
vmlinuz to vmold (or whatever you prefer) then make an entry in
/etc/lilo.conf for it like

image = /boot/vmold
  label = old
  initrd = /boot/[initrd]
  root = /dev/[hard drive partition]

If you have Red Hat, you can just use linuxconf as I usually do. 

Then, if yor new kernel dosen't work, simply type 'old' at your lilo
prompt to boot your old kernel.
