So I guess something like this would do it:

At every request for Debian menu, instead of doing a Popup /Debian, we
would do:
  PipeRead fvwm2-refresh-menu popup

and fvwm2-refresh-menu would be something like:

--------
#!/bin/sh

if [ ! -e $HOME/.fvwm.debian-menu ] || \
  [ /etc/X11/fvwm/menudefs.hook -nt $HOME/.fvwm.debian-menu ]
then
    cat /etc/X11/fvwm/menudefs.hook
    cat <<EOF
# Add in user additions
Read /etc/X11/fvwm/main-menu.hook Quiet
Read .fvwm/main-menu.hook Quiet

# Tack a quit entry on to the end; this version uses a pop-up menu to ask
# the user to confirm, MWM-style (?).  The second line may be changed as
# indicated to use a popup form instead.  (The QuitVerify form is defined
# in system.warnings, read in later.)
AddToMenu /Debian
+  ""            Nop
+  "Exit Fvwm"   Popup Quit-Verify
EOF

    touch $HOME/.fvwm.debian-menu
fi
if [ "$1" = "popup" ]; then echo "Popup /Debian"; fi

exit 0
--------

Then if a user wants to pre-initialise his Debian menus, he can place
a PipeRead command in ~/.fvwm/init-restart.hook.  (This would close a
bug open against the fvwm package.)

This won't work for fvwm1, though (doesn't have a (Pipe)Read
command).
