By the way, AMD makes the use of amd_bitalign() obsolete for rotations, so it's safe to use rotate.
That is not an accurate statement. We have not had to use that since SDK 2.2, this was for 2.1 only. 2.2 or later on any hardware optimizes rotate correctly.
And it seems BFI_INT patching is not needed anymore for 7970 cards, did you observe that, too?

Yes, which is why I added that driver name whitelist. cgminer has also copied that whitelist as well.
