I have a 2.3GHz dual core PowerMac11,2 running FreeBSD 10.2 PPC64 on a ZFS root. My machine has 8GB of RAM and works brilliantly. I tried all flavours of PPC linux and none of them worked particularly well. FreeBSD 10.x had the advantage of 64 bit support and the nvidia 6600LE works acceptably with the open source drivers. I highly recommend FreeBSD 10.x PPC64 to anyone with a G5 PowerMac who wants to run a modern OS.
