certain recent developments,

such as this, and this and this

have made me wary of my complacency with osx.

i'm about to reluctantly take the leopard plunge anyway, but more than
ever, my goal is full-transition. since the beginning i was quite
partial to the bsd way, and freebsd has been my first unix, and will
continue to be my server os for a long time. but now i intend to
channel the full power of this 400mHz g4 into desktop worksation
undertakings. most of the multimedia/graphics stuff i use is
opensource anyway, so it was only a matter of time.

i'd like to know if anyone out there has any info on how to establish
a dualboot osx/ppcfreebsd machine. any and all help will be greatly
appreciated.
