Hi,
Does the kernel load internal built in modules (obj-y) in a certain
order, or in a random order? Does the kernel internal module loading
based on a configuration file?
I am running an ARM system, is there a way to delay the Ethernet module
loading until some other internal modules are loaded?
Thank you.

Yes. As far as I can tell:
- special ordering (when you find __define_initcall in the
kernel source, you know)
and
- linking order
play a role.

/etc/modprobe.conf, but the proper answer would be "no".

I am sure you can use some modprobe magic, such as:
install 8139too /usr/local/bin/my-8139-loader
And your 8139-loader contains:
#!/bin/bash
while ! condition; do
sleep 1;
done;
modprobe 8139too;
I just don't know how well that fares when you are trying to modprobe
from within modprobe.

Yes, it follows some rules.
Please refer to the "3.2 Built-in object goals - obj-y" section of your
kernel_source_root/Documentation/kbuild/makefiles.txt
