I have had no problems at all, and I have heard from a few other, none
of whom have had a problem.

I have not tested as to whether it really improves power consumption,
but it does not seem to cause any problems. At least one person has sent
a note that it really did not make a difference for him, though. But I
have no reason to think that it should not be MFC'd.
