If you've got a patch that doesn't break anything else (in particular
in non-mint8 land), I think it has a real chance of being
incorporated.  Otherwise, it will be tough.  I don't think there are
any free resources anywhere to maintain -mint8 beyond the state it is
currently in.  (And no, I don't want to see it ripped out, simply
because it has proven to be useful at least to /some/ people, and
there's no additional work involved in keeping it in.)

Never trust an operating system you don't have sources for. ;-)
