ALSA is purely userland stuffs, much like other things like SDL,
pulseaudio, arts, jack, yada yada, so on. All you need to do is grab
plain alsa library, replacing alsa kernel call -> oss ioctl (much
like NetBSD/OpenBSD did with their sunaudio -> liboss), and produce
appropriate libalsa depending on your target (linux binary for linux
apps). Leveraging hardware features provided by ALSA call is a
different story, though.
