We run the exact same code on the efika as on the pegasos for example, and the efika uses the MPC5200 which has a 603e core. The 601 i guess nobody wants to use anymore, it was not yet really powerpc, and has a few things missing. The linux kernel has a special case for the 601 for example. Friendly, Sven Luther
