TV-out only ever sort of worked on avivo-based radeons, so we
eventually disabled it.  You can revert that commit and attempt to use
it, but it sounds like you didn't have much luck.  TV-out has not been
a high priority so we haven't a chance to dig into it much more
lately.  Once we get r6xx/r7xx 3D out, we hope to revisit tv-out.
