I think it would be beneficial to spend a bit of time documenting the
supported hardware and composition going forward.  I have no personal
preference on the bit-size issue, but it wasn't communicated on the
list prior to my asking.

Additional items to cover are:

1) Are ppc32 machines supported?  Specifically I'm thinking of Apple
G4 machines, but we used to build a bunch of Freescale device drivers
and such as well for machines in the 6xx class.

2) Which machine type are supported?  Seems POWER7, possibly POWER6
and 5.  I would imagine we would want to explicitly drop PS3 support
given it's limited memory (vs initrd) and the fact that it's not
really sustainable as a machine due to firmware changes.  However, do
we support Apple G5 and Powerstation machines?  (I think yes, but it's
unclear).

3) Which arch is the primary on 64-bit (seems ppc64)
