Screenshot of gears

When HyperZ is used on my RV570 the lower part of the screen isn't rendered
correctly.  I'm attaching a screenshot of glxgears, but it's also visible in
most real-world games and apps.

I'm not sure if this is the same as bug 29851 since the hardware differs.

(HyperZ gives a pretty nice performance boost otherwise, about a 30% fps
increase with Doom 3 in 1680x1050!)
