No, I don't have anything for OS X.

Well, if you don't know the chip well and don't have specs, it will be a
hard time to get that stuff working I'm afraid. You should look at the
initial dual head work for r128 cards that Alex Deucher
<email@example.com> did for X.org, since you need at least that
(dual head) as a first step to enabling TV Out. Then, I suggest you look
at the open-beos project (I think it's on SourceForge) for the radeon
code that drives the TV encoder.
You chip is a Mobility M3, that is an r128, and I think the TV cell in
it is similar to the one in Radeons.
