This is a known problem with the radeon driver.  I'm not sure what the
proper fix is and I haven't had the time or content to actually dig
into it.

So the problem only occurs with the IGP card, and not the 9600? 
Perhaps the older radeons do not support the full 2048x2048 overlay. 
I'll have to check the spec.

Is surround view basically just multi-head using the IGP and the AGP
card?  If so it should work with xinerama for 2d.  3d across multiple
cards is not yet supported.
