Nice one David! Thank you so much :)

I fixed the ACL issues in osspd the other week, so users should be able
to use the /dev/dsp device quite happily now without any hacks.

There are still some experimental patches (to cuse, kernel and osspd
IIRC) that will enable mmap support which *should* be the final missing
link for full OSS support in some games.

At some point after mga2 we might want to consider dropping oss support
fully, except via osspd, and thus soundwrapper might eventually be
unneeded... but that discussion certainly doesn't need to happen today
and it's not really a problem either way in my opinion - just a matter
of how "progressive" we want to be :)
