Will Darwin be Ported to the IBM Power 4?

eadint asks: "I have heard rumors thorough the net that Apple plans to port Darwin to the Power 4, 64 bit chip. Currently I work for a university. We are using Apple computers and are considering the platform for our number crunching capabilities. According to this Motorola has no plans on producing a 64-bit chip. Does anyone know if Darwin can or will be ported to a true 64 bit platform."
