Well, I've now got everything together for a "proper" Debian Raspberry PI
installation. Apparently since 5.2 (perhaps earlier, but 5.2 is
confirmed), Debian's kernel source packages have had their Raspberry PI
device-trees garbled. I do have full untouched Linux kernel source
handy, but I tend to stick with the distribution until that proves
untenable.

This plus adding the devicetree setting now turns into a report
elsewhere...
