Building a macppc bootable USB image

[David Brownlee <abs%absd.org@localhost>]

Technically it should be possible to generate an image which could be
written to a USB device and booted for a large chunk of macppc
machines, and would make it very much easier for people to try and
install NetBSD/macppc.

Ideally we should be able to include something in build.sh so standard
NetBSD builds could include an install and/or live macppc image
similar to amd64/i386.

Does anyone have the time and inclination to look at any of this?

Would a small payment for the time help?
