Jordan K. Hubbard 9be435aa17 Break my own rule again - I didn't think this stuff was going to come back
with the copyright stuff fixed so soon (this should be merged into 2.2 when
you have a chance, Poul).

This is the new AWE32 driver, with support for the AWE32's fancy MIDI
synthesizer.  The utilities for this will appear as port submissions soon
afterwards, according to the submitter.
