no, this patch is for e1000, and has nothing to do with this problem.
Right now, the only reports of this issue are with 82566 and 82567 based
LAN parts (ich8 and ich9).

the eeprom is not MMIO mapped, the registers for accessing it are. I'm
still not clear if a random write to a memory location could corrupt
things, we'll be looking at that today.
