I cannot find one either. But that doesn't necessarily mean that it would be more difficult to do. It could also just mean that nobody did it for AROS on PPC yet due to lack of request and/or motivation and/or available PPC hardware. As far as I'm aware AROS on PPC generally lags behind AROS on x86.
