Note that I never said the various CONFIG_* options have to be mutual
exclusive. Enable them all for a generic kernel for a distro, enable what you
need only for a machine-specific kernel.

PowerMac kernels should work on PReP and CHRP as well.

The rest is unified. But it's so unified that I can't get rid of e.g. all
PowerMac-only code when I want to compile a kernel for a CHRP box. Much
PowerMac specific stuff is indeed freed up later when the pmac section is
released, but that's all.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
