by the way all ppc are neutral, you only have to set one bit in order to change the endianness
My understanding is that existing Mac OSX for PPC does not support the the execution of little-endian PPC programs without jumping through hoops, which is infeasible for normal PPC programs. So infeasible, that there is (only?) one such program, Virtual PC, the version that works on CPUs prior to and including G4, but not G5. VirtualPC is probably using assembly instructions and/or installs a driver to execute little-endian program code under OSX in order to emulate a Pentium x86.
One cannot even use the "-mlittle" GCC option to produce a PPC binary to run under Mac OSX, "-mlittle" is only for embedded PPC CPUs.
The G5 processors do not support little-endian mode -- that's the reason Microsoft took so long to port Virtual PC to that processor.
