You would be more likely to get an answer (perhaps even a useful one) if you could be a bit more specific what it is that's tearing...

IE; is it 3D or overlay? The CVPPC driver doesn't support doublebuffered overlay, so tearing is inevitable (this could probably get implemented if you motived the right core developers (bigfoot or cyfm I guess (I could probably do it if I had a working A4k as well. :P )))... 3D shouldn't tear with the latest TinyGL AFAIK (though maybe it depends on the app).
