From NetBSD, Lennart Augustsson <augustss@cs.chalmers.se>:

Add a driver for the Ensoniq AudioPCI sound card.  The driver still
needs some testing, but it seems to produce sound.  The driver was written
by me, but since I don't have the hardware the debugging and testing was
done by Andreas Gustafsson <gson@araneus.fi>, Chuck Cranor
<chuck@maria.wustl.edu>, and Phil Nelson <phil@cs.wwu.edu>.  Thanks.
