FYI, I got in touch with a MOL developer and asked if my little experience 
in C++/C would be of use to help port MOL to G5. His answer below suggests
that it will take some time until we have MOL on G5 :-( Anyway his brief 
answer (I'm not good at assembly level code). 

"Well, adding g5 support is highly nontrivial. It requires a rather
extensive reconstruction of the assembly level code (src/kmod/*.S).
