The PS3 "port" (stage 4) that you're talking about was a test build done
by one of the PowerPC team developers, Brent Baude, and isn't an
official release, (as far as I know).

As for a real port, the basic install can be easily done with the
generic ppc/ppc64 stages that we already make!  Simply install the
stage3, and recompile the whole system using "emerge world -Duve",
although you may want to rebuild the system targets first.  There is no
need for additional stages.  By giving you the ability to install on a
multitude of targets, while still allowing for optimization and
configuration, well, that seem like it meets the Gentoo ideals and
philosophy!

That said, we probably do need to make an updated minimal install CD for
PS3 if one doesn't already exist.  Unfortunately, the PPC team doesn't
have a whole lot of man-power at this time, so that will get done as
soon as someone decides that it needs to be done and has the time to do it.

Again, you can use *any* LiveCD (even other distros!) to boot the
system, but the current PowerPC stages are adequate to complete a fully
optimized Gentoo on PS3 install.

Hope that helps,
-Joe
