iirc, for the purposes of the test, we could just set the stride to 512
and be done with it. The idea behind the test is to simply require a
fence register and then since we compare the same tiling pattern in
both, the actual tiling is irrevelant. (I wonder if using different
strides is of any value, not sure that it is - it doesn't change any
code paths).
