hehe, I believe you :)
Under such severe constraints, it is probably better to use a PC speaker
type of emulation :P
But seriously. It is probably more work then a real driver, but can be done.
Even more: You can only implement the stuff that can be done. ALSA is
completely run-time driven, and applications are expected to query the
capabilities of the sound cards.
So, you probably won't have a midi interface, but at least raw audio.
After doing that, you can try top use timidity or so...
In this situation, I don't believe m68k people could add much to Alsa
design, which is centered around latency of midi signals and other profi
sound stuff... OTOH, alsa is flexible to support also small sound
environments, without much features. It will certainly be easier then to
integrate it in OSS!
