For starters, upgrade kernel?

Anyway,

In the lilo prompt, write:

  Linux init=/bin/bash

(that is: add the extra parameter init=/bin/bash )

This will boot the system and give you a shell before loading any
modules. 

Now in there, run:

  mount -o remount,rw /

and probably also:

  mount /proc

Do whatever edits are required so the zaptel modules won't load (editing
/etc/modules, or even moving the module files from the kernel dir) , and
then:

  umount /proc
  mount -o remount,ro /

  exec /sbin/init

The boot process should continue normlly (this is /sbin/init running as
process 1).
