Did you build e1000 as a module or in the kernel?
In the latter case, it is normal that modprobe says nothing and that you
cannot see e1000 as a loaded module.

You can check with:
grep E1000= /boot/config-... (the config file saved in /boot after building
the kernel).

If you get:
CONFIG_E1000=y, it is not built as module, but embedded in the kernel.
CONFIG_E1000=m, it is built as module.
CONFIG_E1000=n, it is not built at all.

Now, coming to the issue you have, it may also be that eth0 is renamed to
something else.

What does 'ip link list' return on the booted system?
