There are certainly sites that'll do this (checkip.dyndns.org for
example). Also, if you do go with dyndns or equivalent, the little
program that tells dyndns when your IP has changed may well be able to
query the dsl-modem for the IP. I use ddclient and it supports a fair
variety of routers and such natively, along with the option of hacking
together a regexp if your hardware isn't on the list.  As long as your
interface has a "status" page that lists the WAN IP on it somewhere, you
should be able to cobble together a way to retrieve it without
resorting to anyone's external web page.
