OK, both of these options are AWESOME.  Thank you and hiro so much for
pointing me in this direction.  I'll have to stand up another 9front
box or VM to get my acme feel-goods on while I'm working on this, but
that's so much better than what I thought I'd be doing.

FWIW, I dug up the Raspberry Pi 3B+ schematic [1].  It looks like PWM
is what's tied to the onboard audio output, not I2S.  The PWM register
addresses [2] look like they start at 0x7e20c000 and match the BCM2835
ARM Peripherals spec from earlier.  I've... got my work cut out for
me, but it'll be a learning experience.  :D

Thanks, y'all! I really appreciate it.
