Looks like DM111 offers PPPoE/PPPoA "bridge" modes which sound like what some other boxes refer to as "half-bridge" or "DHCP spoofing", and also standard RFC1483 bridging. If the modem can connect when it's set to PPPoE (which is sometimes possible even when the ISP normally uses another method e.g. PPPoA), you should be able to change it over to RFC1483 bridging and setup a pppoe(4) interface ("man 4 pppoe") on the OpenBSD box. Obviously, if the only net access you'll have at the time is via this modem, make a note of current settings and any instructions you might need to reset things before fiddling. :-)
