Well, the first thing I did was to strip down the unix kernel into
something which was suitable for statically linking into the
mol-of image (which doesn't link against anything). In particular,
there is no plug-in interface (dlopen is not available for
one thing).

All that is needed really is a hook once OpenFirmware has initialized
itself. One can do some stuff just before calling initialize
although the OF memory stuff (and probably more things in the
future?) is not initialized at that point. I think the best
thing would be to invoke a hook (if defined) just before
quit is called.

Or one should perhaps add a more generic system for static
initializers. I bet that other parts of OF will need some
eventually... (nvram parsing, device tree probing etc).
