I think you need a lawyer, or at least the author of the MPL, to
answer that.

It wouldn't have got through in the last few years without a lot
of obvious negative comment, so I don't think it is approved.
Note that the only official purpose for this list is obtaining
such approval, and that is best done by a request by the author
of the licence terms.

The BSD licence with the advertising clause is open source, so I don't
think there is any absolute bar.  However, such a licence would be
incompatible with anything more restrictive than a BSD licence, so 
I would expect it to be shunned by the open source community.

Generally people want licences that allow one to extract code and
use it in other contexts, e.g. ones in which there is no rastererised
user interface.

I doubt that they mean copyright notice.  The copyright notice tends
to be, at least in part, a property of a specific version (I guess
it could vary if the copyright ownership was assigned).  I wonder if
they mean the licence terms?
