OK, so to get MIDI and adlib output, we have to make this flexible,  
and port the "scumm adlib" and "scumm MIDI" drivers from the "FreeSCI- 
ScummVM" gsoc code base, I guess?

Also, I think you or somebody else hinted that in that code base, the  
realtime player is also used / usable for regular audio output, albeit  
buggy. Right now, the polled driver works fine, but if we could get  
everything to work with the realtime driver (without regressions, mind  
you), that would of course be nice: Then there would be no need for  
switching, and a single code path to test.
