Thinking about it further, I don't think I ever transitioned this system to
grub2, and it had been happily using grub.

The setup I ended up with after the upgrade was this:

ii  grub           0.97-29ubuntu5 GRand Unified Bootloader
ii  grub-common    1.97~beta4-1ub GRand Unified Bootloader, version 2 (common 

with /usr/sbin/update-grub missing.  Here's my best guess at what
happened:

1. grub/grub-common were installed, with /usr/sbin/update-grub present

2. Something caused grub-pc to be installed while it did not conflict with
   grub, and grub-pc replaced /usr/sbin/update-grub (grub-pc Replaces: grub)

3. /usr/sbin/update-grub from grub-pc was being used for a while, updating
   grub.cfg and not menu.lst (but I didn't notice because I didn't reboot
   for a while)

4. The most recent upgrade opted to remove grub-pc in favour of keeping
grub

5. /usr/sbin/update-grub was removed along with grub-pc, leaving nothing in
   its place
