Have you tested that the resulting kernels work on the relevant
hardware?

The old drivers may be crufty but they presumably have been tested by
people and at least somewhat work.

So I'd be inclined to leave the defconfigs alone until someone can test
that the new driver works at all.

I gave it a quick spin on a G5 I have access to and dmesg has a bunch of
errors in it (see below). I can't actually tell if the display is
working because the machine is remote, and I can't go and check it at
the moment because the office is closed.

cheers
