I have tried to port coreboot to asus-p5g41c-m-lx by using the existing pg541t-m-lx variant. Everything works great except I cannot get the onboard lan realtek 10ec:8168 to be detected by coreboot. The card shows up and works once linux boots. Adding some register values in the overridetree.cb seems to disable the card even in linux. Please let me know what supporting info I should provide. 

Thank you
