Huh... This is weird. Does vsync work for other programs?

try this as a normal user:
__GL_SYNC_TO_VBLANK=1 glxgears -printfps

It should print exactly the vertical refresh rate of your monitor. If it 
doesn't, there's probably something wrong with your driver setup.

I don't mean to shift the blame on others ;) But this sounds a lot like a 
buggy driver. I too have seen one or two complete lockups while resizing 
the jack_oscrolloscope window. I guess that's what you get for using a 
binary driver on a -rt kernel it wasn't made for...
