I think that this is a "yes" to your first question:

As to what I had to do, not much; just compile a kernel with the
lastest sources and lo, it just works.

Now, there was an issue a little while back with some USB code that
Julian had to adjust; once his fix went into the source tree, the
issue vanished.

IIRC, that was shortly before 5.4 was released. The machine is
currently running 5.4, with fresh (about one week old) sources.

I don't care what you think. This is not a stylishly insouciant stroll
out of the jungle, here. It's more like we've fallen out of our trees
and rolled, butt-naked before the entire galaxy, downhill. That, and
we seem to have a teensy problem lifting ourselves off the ground.
