atually, now that i think about it... mac should be as easy as finding a patched dvd image like the one from x86 project.  It is a PPC machine so the only thing stopping a person from instaling it is the os/apple chip relationship.  As soon as I get a hold of a ps3 thats the first thing i will be doing to it...  sticking the patched ppc osx build in it and seeing what happends.
