I pulled the firmware files from https://github.com/RPi-Distro/firmware-nonfree, and loaded them on a v20180322-090018 image in the /lib/firmware/brcm directory. Using the same wpa_supplicant config that I use on my RPi 3B systems, the wifi now works.
The wired ethernet is still down, but one network interface is better than none. :)
