I build my own kernels from source so I might be off, but don't the
stock 2.4.x kernels require you to boot with initrd? That could
explain your kernel panic. The drivers necessary to get to your hard
drive, or the file system of your root partition, may not be built in
to the kernel you installed. 

With initrd the kernel will boot with initrd, load the modules
necessary to continue booting your system and then proceed to boot
from your root file system on the hard drive.

Unfortunately, since I don't use initrd, I don't know how to fix your
problem. In all likelihood the best way to go is to let the
kernel-image installation modify your lilo.conf itself and then make
the modifications you desire after the installation script for
kernel-image has done its thing.
