I don't know. I didn't pay much attention to non-X stuff, but the changes
outside of xfaces.c are very small and I think they're all in generic code,
so it may just work.
I tried to avoid changing all the uses of DEFAULT_FACE_ID because as you say
there are lots of them.
The cases where DEFAULT_FACE_ID need _not_ be changed are:
(1) Where the face-id is passed (eventually) to init_iterator, as
init_iterator will do the work (the face passed to init_iterator is not
a `real' face-id anyway, it is required to be one of the basic
face-ids).
(2) Where the code really wants the underlying default face, not the
buffer's default face. An example of this might be where it's going to
test whether it can just draw the background color -- in this case you
want to treat a remapped default-face as just another face (i.e., not
the background).
Those two exceptions cover many, many, uses.
There are a few I'm not sure about, e.g., the fringe munging code, but the
patch tends to fail conservatively, so the only effect might be that
remapping doesn't take in some cases (like the fringe face).
