Well, I've checked with my ilk and snb, and now it works for both. ymmv.
The other options is to return SWIZZLE_UNKOWN back to userspace and
disable the tests on gen5+. I don't care too much either way, but I think
making it work is less risky. And now that qa actually runs our tests, we
might even catch this earlier.
