The most effective way I have found to speed up Minecraft on PowerPC is to host a local server on a separate machine. I believe that the majority of the slowdown is caused by the server generating/updating chunks, rather than the client rendering the scene (as shown by the debug profiler).
I get around a 100% increase in FPS on the same map - YMMV
Hopefully I will get round to doing a proper write-up and video soon - in the meantime - enjoy!
