I've got an Origin200 laying around not doing much (outside of running oracle anyway :) I can build the toolchain on if someone wants to give some instructions. It's not Sun, but it is 64 bit. I also have an LX doing nothing (literally) which I can put a few things on. Not 64 bit, but it is a sparc.
