Patch looks right...

If you are right that the K6-2 and K6-3D support 3DNow!, then yes. At least its "correct" but it may not be optimal: I seem to recall 3DNow memory copies were not worthwhile on anything before an Athlon. Double check that, though.

Yes. Even if the above is true, splitting the K6 out like this is useful for the extra -march here. It certainly does not hurt (picking the original K6 will give proper support for the whole family, in needed).
