	Note this using the newmidi that's currently available in
fbsd.  It can read/write on the raw port (/dev/midi%d) and writes to
the sequencer (/dev/sequencer).
	A simple test would be
	dd if=/dev/midi0 of=/dev/null bs=1
	Which should produce a stream of bytes corresponding to active
sensing requesting (provided they aren't filtered) and note on /note 
off events.
	Also, you should see irq's for reading.  (provided your
equipment is connecting, you will get an irq 3-5 a second while the
keyboard is connected, 0 while disconnected)
	Playmidi should compile in the ports by changing the
#include <dev/machine/soundcard.h> to
#include <dev/sys/soundcard.h>
	Then play a .mid file.  

	emu10k1 provides an mpu401 which should be relatively easy to
support as far as midi hardware goes (since the code already exists).
