Are you sure that you´ve configured your ethernet driver? There is no MAC address defined. And the PHY address is really located at 0x0 or 0x1? If not you have also to configure the offset from which address the PHY routine start in your board specific files like for OCOTEA reference board in linux-2.6.12/arch/ppc/platforms/4xx/ocotea.c
