If you have two cards (a very common hardware), and PXE booting is
done from the "first" card which the kernel defines as eth1, it's a
perfect solution to tell the kernel ethdevice=eth1.

The kernel itself does not know anything about were it was loaded
from. It even does not know if it was loaded from network or disk or
whatever device.
