Right. If I understand correctly, SDL choked when trying to use
PulseAudio as its ALSA device, so we used a last-minute workaround of
forcing it to use ESD. See this thread for details:

A preliminary driver was written in April:

I dunno what the status of that is now, but Lennart has said that we'll
get native support by F9. Let's hope.
