I know for certain C and LLVM work. I'm quite sure there is no implementation of a JVM backend. Samuele Pedroni is working on PyPy as well as providing some continuing guidance and code to Jython -- he would surely have mentioned such an implementation. The theory is another matter -- I'm sure this would be possible to implement, but PyPy development is very active right now and might be a bit of a moving target.
