I would like us to use generic dummy frames for both cases.  This
is one of the things I wanted to do last February, but I didn't have
time to test it.

I see your point.  After you've applied the BFD changes (and any other
pending changes -- I've lost track), feel free to apply your mega-patch.
Then clean up from there.  (Again, let me know when you've applied it,
so I can take a look at fixing GNU/Linux/PPC.)
