I am actually a lot more concerned with the fact that we don't test
for invalid bits.  So we have an ABI that will change in the future,
and that doesn't allow us to have a program that runs on old and new
kernels.

I guess I can resend some version of my patch after 2.6.16 is out and
break the ABI for the undefined bits then.  Correct programs shouldn't
care.  But it sure would be nice if they could care.
