Similar problem on 2.6.34 (gentoo- and zen-kernel).
To my PC connected monitor (DVI-0) and TV (S-video).
Monitor display is ok.
TV display fine with radeon.modeset-0
With radeon.modeset=1 screen has horizontal line (like
http://bugs.freedesktop.org/show_bug.cgi?id=26915), but patch
http://bugs.freedesktop.org/attachment.cgi?id=33809&action=edit dont fix it.

This bug relates to a very old kernel. Closing as obsolete.

Please reopen if seen on a modern 3.x kernel (3.10+ say)
