With libreboot re-installed, it's working for me as well!
I haven't tried just applying the minimal patches and/or configuration
on top of Guix's linux-libre, but that seems like a logical next step...

To be clear, this feature doesn't actually make a serial console over
USB, it somehow "rewires" one of the USB ports to have a ground, rx and
tx serial-ttl pinout. So you pretty much need a custom USB-A plug and
solder/crimp the bare wires to a serial-ttl adapter. Slightly more
details in Documentation/admin-guide/kernel-parameters.txt.
live well,
