Which pcnet32 chip are you using ? There are some issues with
auto-negociation on some integreated-PHY models, and you may have to
adjust a few of the chip parameters. I used the pcnet32 driver with an
AMD 973 on an ARM platform and it worked just fine (after I fixed the
cache coherency issues but those won't happen on PPC).
