debconf needs to start its frontend when it starts, even if the frontend
is never displayed.

Well perhaps a screenshot and a list of all the gnome libraries and
debconf's dependnancies and so on. There's suposed to be a little down
arrow after those, and drawing it is not something that debconf does,
it's all done by the underlying libraries.

Debconf goes a long way out of its way to detect broken X displays and
fall back. It goes as far as forking off test processes to see if the
display works. It does all it can, gnome does not offer much in the way
of control over how it uses the display.
You appear to be suing to root and getting DISPLAY set to something that
root cannot access. In all my tests, debconf detected that and fell back
to a text frontend.
root@silk:~>unset XAUTHORITY
root@silk:~>dpkg-reconfigure debconf -f gnome
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
Gtk-WARNING **: cannot open display: :0.0
debconf: unable to initialize frontend: Gnome
debconf: (DISPLAY problem?)
debconf: falling back to frontend: Dialog
