The problem appears in rc1 (where the TPM is added). Unloading the module doesn't help, once it has been present the system needs a reboot for the network card to function properly. I don't really see how the TPM can screw things up for the network card but I'm guessing it breaks something in the chipset (the TPM module gets loaded for the LPC bridge).
