You can add a "howmany=X" line to menu.lst to limit the number of
kernels that grub1's update-grub adds to menu.lst.

Based on
http://www.mail-archive.com/grub-devel@gnu.org/msg13049.html
it is unlikely to be added by the grub developers. It seems to have
been a Debian/Ubuntu customization. I do not have a grub1 install to
look at its update-grub script but I remember it to consist of more
than the grub2 update-grub script, which is a one-line grub-mkconfig
invocation.
