Btw, please consider that ports to new host platforms really benefit
from SDL for those things. For example we've been using SDL for the
Haiku port until last year:

http://bb.haikuports.org/haikuports/commits/df441da15a7c4a5583f6460de2ca1d570d0caee1

All other backends are either *nix only like OSS (Haiku has an OSS port
but only uses its drivers, the API is not made public), or even
Linux-only like PA or ALSA. There are more OSes out there than just
GNU/Linux :p

It's already hard enough to get stuff upstream into QEMU, having to
write native audio and graphics backends before things get usable won't
help at all.
