I've seven nForce4 PCs (ASUS A8N-E), and no problem with the Ethernet ports (all communicate with >100MB/s when using netcat).
Mobo specs usually mention some PHY chip in connection with the gigabit ethernet. Common is something marvell, and CICADA8201. Does this PHY thing affect the kernel device driver at all, or is it some kind of line transceiver like the historic MC1488/89 for RS232C? Because if it doesn't affect the software, one can conclude that the gigabit ethernet on nforce4 chipset mobos works reliably with 10.0. Did you test all the other peripherals on this Asus A8N-E? Specifically, does SATA work OOTB? How about lm_sensors?
