Maybe the PPC keyboard/mouse drivers do not add randomness? You should also get randomness from disk I/O. If your PPC system is diskless, mouseless, and keyboardless, there is also a patch for 2.4 which allows you to get randomness from network card interrupts, which is good enough for all but the most incredibly paranoid people.
