What were the problems? Couldn't userland just have both cpu/powerpc and
arch/powerpc go into /usr/includes/machine, or was that not the problem?

If we can't split things up that way, how about we change one of the two
names? Either make the computer be ofpowerpc or ofppc, since it is a port
to full-fledged Open Firmware PowerPC machines and not the pseudo-OF
machines we buy from Apple, or make the cpu-specific stuff arch/ppc?

Take care,
