It should, but vsync problems on modern Linux boxes seem to be a 
nightmare...

What video card driver are you using? AFAIK eg. nVidia has a similar 
option for its driver which may override an application's request, and 
driconf also has similar settings. Tearing in videos (xv) is most 
probably independant from this setting and needs to be configured 
elsewhere, with video drivers for eg. Intel graphics chips you need to 
select the correct xv device out of the two which are known by X11 so 
vsync can be controlled... :-/
