The Xv output produced by the radeon driver (6.14.4) in Debian wheezy appears to be not vsynced on my Radeon HD 4670; tearing shows up.

xvattr says that XV_VSYNC is 1. Using mplayer to play a video with its gl output option is properly vsynced, as are other OpenGL-using apps. When using the xv output option, tearing occurs.

Attaching /.drirc (vsync enabled), output of xvattr and xvinfo (XV_VSYNC 1), and Xorg.0.log.

Attaching make_flasher.sh, a script using mencoder and ImageMagick to generate a flashing avi to make the effect particularly obvious. Playing this avi with "mplayer -vo xv build/output.avi" produces tearing, whereas "mplayer -vo gl build/output.avi" does not.
