e1000e not found, dead board?

I have a motherboard with Intel e1000e gigabit ethernet built in. This morning when I turned the machine on, no eth0 device could be found. What the hell? Everything checked out fine, and it was all running the day before. Eventually I noticed that when running lspci -nn -vv, it showed the ethernet PCI device Id as 8086:0000. Luckily, I have another of the same board, and when I run the same command, it should be 8086:294c. Weird. Then I kind of remember that I might have static shocked the case the night before, but not too sure. Anyways, I went into the kernel source code and changed /usr/src/linux/drivers/net/e1000e/hw.h. I found the line with 0x294C and changed it to 0x0000, recompiled, rebooted, and it worked fine! Is this motherboard dead? Looks like its beyond warranty repair. Just live with it? Or can the device Id be changed?

Not sureif this wil help, just in case:

This happened to me when I upgraded my HW. BIOS setting was set to Green LAN, meaning that if no "link" present while system starts the NIC is disabled and no way to enable it by software. This made me crazy during first boots, etc, as I was connecting/disconnecting cables at the same time. Just placed Green LAN to disable, so the NICs are allways up.
