That's true in your case, as you chose the LILO way. Generally
speaking, however, GRUB is much more flexible. I think it always makes
things complex to obtain flexiblity (e.g. consider autoconf vs. imake),
and that's not so bad to have as a trade-off.

Anyway, I can write what you need very easily:

[add-kernel menu.lst title kernel_cmdline]
#! /bin/sh

menu=$1
title=$2
kernel=$3

tmp=/tmp/sed-script-$$

# Find the first occurrence of entries.
where=`sed -n /title/= $menu | head -1`

# Make a sed script temporarily.
cat >$tmp <<EOF
/lock/d
$where i\\
title $title\\
kernel $kernel\\

/title/a\\
lock
EOF

# Execute it.
sed -f $tmp $menu

# Cleanup.
rm -f $tmp
[EOF]
