I think the real answer to this is to have a separate partition
for /boot which is common to both Dapper and Edgy (note, I've never
tried this).

At the moment, you have two copies of /boot, one in the Dapper partition
and one in the Edgy partition. When you upgrade Edgy, it will update the
menu.lst stuff in its /boot, if you upgrade Dapper it will do the same
in its /boot.

You should be able to have a single /boot partition. You will have
images for both Dapper and Edgy in there and a long grub menu allowing
you to boot from any one of these.

Like I say, never tried it and I don't know if there are any gotchas. Of
course, it means (probably) re-installing everything and re-partitioning
which you maybe do not want to do!
