It's not available in Lion. I believe that it used an ioctl which is
no longer supported.

I don't believe ACLs are evaluated when you're running as root so I
would guess that it's something else that's stopping you. It could be
the immutable flag (which is checked when running as root), or it
could be a Kauth or Mandatory Access Control plug-in. For example, on
a Time Machine volume the TMSafetyNet kernel extension will prevent
you from doing anything to it (which you can disable if you really
need to).
If you're not sure exactly what is stopping you, you could use dtrace
to watch various Kernel methods (which has helped me in the past).
And, of course, all the source code is available.
Kind regards,
Chris
