There's nothing to bisect. The issue is exposed by advertising 256x256
cursors by default. But older kernels supported 256x256 cursors as
well, which is why modetest was a good test for it. modesetting ddx
takes the "default" cursor size.

It's just a matter of figuring out which hardware has the problem.
