i am not sure, why the OBP says network to one and to the new card ethernet, perhaps that's the reason, why show-nets doesn't recognize the new one... could imaging that you would need a newer firmware, but couldn't find a hint for that....

but that ce driver is not the right one. ce is for Cassini Gigabit-Ethernet devices, your X7285A is an Intel PRO/1000GT chip, so you will need that e1000g driver... GigaSwift is the name for another card (e.g: X4445A)
