I guess I don't really understand what you expect to happen between now
and beta1.  The chances of an lcd filtering patch landing in cairo
master in this timeframe is minuscule and even if it did, there'd be
hardly enough time for testing.  So we're limited to the patch that is
out there right now.  I only see four options:

(1) --enable-system-cairo
(2) Get someone from mozilla to ack the patch that we've been shipping
in cairo for ages
(3) Take a page out of debian's book, apply the patch and just don't
call the browser firefox.  This needs to be an option, otherwise we have
no leverage for (2).  Or ship two versions of the browser, one that is
called firefox and looks like shit, and one that is called namoroka and
looks good.
(4) Do nothing, repeat the disaster that is bug #217908 and let people
deal with it in PPAs.

Whatever solution is adopted, it's better make the decision now than in
six weeks, in order to maximize testing exposure.  Nothing is really
going to change between now and then.
