I was thinking about a completely different opioin this week.  What if the
config program could make the kernel something like a microkernel ?  For
example, suppose I want to build an embedded BSD (in EPROM) just to make
some kind of industrial process control.  I would not need lots of things.
For example: SWAP, FS support (MFS and/or NFS only !), networking, console,
and maybe even some system calls could disappear.

I have a friend making some tests on this and he cannot make something less
than 300K for the kernel.  It' still too much for such an application.

Just an idea, of course...  :)
