rv670 AGP but running agpmode=-1 as agpgart + gallium locks on this box. kernel d-r-t, git ddx with tiling enabled in xorg.conf. Does not affect my PCIE RV790 box.

Mesa demo lodbias does not work normally since

It disappears to black too quickly between 1.5 and 2.5 and the image is corrupt rather than blurring gradually during this time.

This is a driver-specific bug and the patch in bug 35312 is not a fix, it's a bloody hack.
