=46rom what you're telling us, it sounds like all you need to do is run
'dpkg --purge kernel-image-2.4.bad', followed by 'apt-get install
kernel-image-2.4.new'.  My understanding of your situation is that the
current default kernel is not working and you manually select the
alternate kernel each time you boot.  In this case, purging the kernel
image will remove the /vmlinuz symlink and leave the /vmlinuz.old as it
is.  Then installing the new kernel will cause the /vmlinuz symlink to
be created and the /vmlinuz.old will still not be touched.  (If you were
just removing the newer one, you could 'mv /vmlinuz.old /vmlinuz' and
then re-run lilo.)

If you still have the Debian installation media, they can be used to
boot into your system if anything goes wrong.  I believe at the boot
prompt it would be 'rescue root=3D/dev/hdXY'.  Since you're using
2.4.18-bf2.4 on your machine, it would be the same kernel as what you're
using.

Out of curiosity, what's the new (non-working) kernel?  Does it require
that you specify an initrd?  (Just wondering why it panics rather than
booting.)
