Steve,
Is all that on sources somewhere or accessible otherwise?
Last night, I pulled devbcm from plan9-bcm on github and
folded it into the latest pi image Richard posted on sources,
but I haven't done anything other than compile and boot
a kernel with it yet.  I've ordered a few toys to play with
including a little 3.5" LCD with touch screen that talks SPI.
So I'm going to try to get that up and running soon.

Same here.  In fact, I've ordered a Banana Pi to see just
how close it does come to being compatible.  I'll let everyone
know if it does boot the rpi images.

As an update to the whole thing, I've decided to go ahead
and use the Raspberry Pi at least this term.  Given the time
available, I suspect I'd get too caught up in getting a stable
port running on anything else and not do what I need getting
classes prepared.  If I teach this again sometime, maybe I'll
get a chance to do more.

I will say I very much like the documentation that TI has for
the SoC in the BBB, especially compared to what passes
for Broadcom documentation.  The reference manual for
the AM335X processor is nearly 5000 pages.  And there
are several other things I like about the BBB over the pi,
but who knows when my supply of round tuits will allow me
to spend much time working on it.

My thanks to everyone who has given me suggestions.
There are definitely some new machines I hadn't seen
before that I'll be checking out.
