I'm currently working with Debian 6.01a and the 1.2.20 and 1.3.10a drivers from the Intel site for the 82579 NIC. I modprobe -r e1000e and then insmod /filepath/e1000e.ko. After running ifconfig -a, the 82579 NIC shows up. The problem is after I reboot, the NIC disappears again and I have to go through the modprobe -r/insmod process again. Is there anything that I'm missing here?
Found the answer. Ran mkinitramfs -o /boot/initrd.img-
