thanks for your response.
My first order of business with getting OsX installed would be to get darwin9 installed first. Seeing that darwin is open source I was going to either svn it from apple or use
http://www.puredarwin.org/ Getting puredarwin installed would allow me to get Macports and XFCE, enlightenment..... or whatever Macports has available. When puredarwin is installed it too asks you if you would like to boot from a OsX disc, it references Chameleon in it docs about bootloaders. If any are interested in checking the the ps3/OtherOs++ capabilities please see
http://www.ps3devwiki.com/index.php?title=Main_Page or
http://wiki.gitbrew.org/wikibrew/Main_PageThe petitboot that is posted to get linux installed does not have HFS+ capabilities. I have gotten openwrt and made a petitboot that does mount HFS+ and should boot EFI and supports openfirmware/yaboot. Openwrt also lists support for POWER4 and Mac, IBMblade, Cell which is a powerpc arch.
these are some of my ideas and I just need to get to testing all the different things listed above.
Thanks for your time.
