APM/AMCC Kilauea board broken with 3.5+ kernel

Please correct me if I'm wrong, but I thought that one of the reasons to
bring a board to mainline is that if someone breaks it he/she also fixes
it (at least this is what I tell to the attendees of my trainings).

... but maybe that's not always the case ...

Before the commit[1] it worked, now it does not.

So I guess there are two options:
[] fix it
[] if not even APM cares about their own Kilauea board[2] it should be
thrown out of mainline

[1]git bisect tells us this:
