Your ethernet controller is GMAC, BCM5400 is the gigabit PHY (Physical layer chip) connected to it (other machines can have different PHYs), and you don't need to insmod anything to get ethernet working. (But you should use a really recent kernel if using this PHY since olders didn't support it). ben.
