yes yes yes. i would love that, but... it turns out that apple is
basing their code on motorola's original patch, and they haven't
submitted the paperwork for the copyright.
motorola has a present and future copyright assignment but only for 68k
and 88k. so unless motorola signs off, we can't use the apple/motorola
code base.
i would however, love to coordinate work.
