I'm really against merging more 'not upstream' things.  We make a big
deal about how close to upstream we are, and frankly in the last year
or so, we've _sucked_ at keeping that statement true.
Whilst some stuff is likely to end up in upstream at some point
(utrace for eg), other stuff is perpetual baggage that is a pita when
it comes to rebasing.  Each release, we're getting closer though,
as more and more old stuff gets thrown away.  For eg, for F7, no-one
cared enough about tux to really keep it maintained. Result - gone.
Xen became such a hindrance it ended up having to go to its own package.
The wireless stuff seems to be a sliding patchset, where the stuff it
contains ends up upstream, but at the same time, a new batch of
not yet upstream stuff arrives. I'm hoping eventually that too will
settle down, but adding a driver here and a driver there is a path
that I'd really rather we didn't travel due to the ongoing maintainence
headache that it involves.

A much better way to get this stuff into Fedora is to find out why
it isn't getting upstream, and get involved with whatever cleanup
work is necessary to get it there.
