I think the i855GM TV-OUT was left for dead there. There is currently a ch7017 and ch70xx driver for DVO, but I am getting a bit confused so I don't know if my hardware has a DVO or a TV-OUT (it has a VGA output and a 5pin S-Video output), I'd say the TV-OUT (S-Video output) is the part dismantled in current driver.
I'd suggest looking at these release news: lists.freedeskt op.org/ archives/ xorg-announce/ 2007-November/ 000430. html

There is one significant line by Eric Anholt:
Disable TV/VGA output on the CH7017/7018 devices.
