Sorry for a small comment (not really related to the topic).
I wouldn't call it DSL modem, As far as I know it does not have analog data,
so there is nothing to Modulate/Demodulate. I would refer it as a router or
bridge... I guess...
Feel Free to correct me if I am wrong.
Andrei.

....and the ppp daemon (ppp(8)) can use netgraph to connect to 
pppoe sessions running through DSL. (though it needs a 
ethernet attached DSL modem.)

welllll, start with the netgraph(4) manpage (not netgraph(3))
then you'll find MOST of the implemented nodes in /sys/netgraph,
though there are a couple of others (sync cards)

the mpd-netgraph port (under ports/net) can use netgraph to run pptp
vpns
and the ppp daemon (ppp(8)) can use netgraph to connect to 
pppoe sessions running through DSL. (though it needs a 
ethernet attached DSL modem.)

there is also an article on netgraph on Daemonnews
in the "blueprints (?)" section that is illuminating..

also check out /usr/share/examples/netgraph 
for examples of how you might set up some configurations.

For a very conoluted example you may write yur own setup and control C
program
using the netgraph(3) library to control it. (that's what mpd and ppp
do)
