MIDI on SB Live! ?

[jimd at siu.edu]

I can see /dev/mid* devices under my FBSD-4.8-STABLE system, but I don't see
these under FBSD-5.1-BETA.

Is "newmidi" related to "device midi"? I can't find any "newmidi" entries in
the 5.1-BETA /usr/src/sys/i386/conf files. Or is this like "device pcm" ->
"newpcm"?
