Xorg 6.8.2 does not support tiling. It's enabled for the primary head 
only because it would be difficult to get the tiling regs setup 
correctly for both heads (one of which may have them set up by drm), 
without much reason to do so (since the 2nd head doesn't support dri/drm 
and tiling really doesn't add much if anything for 2d). I don't think 
that tiling only on one head should be a problem, though admittedly I 
didn't really test that... You could try switching it off for the first 
head to get that out of the equation.
