The ethernet shield was always on my list of things run with 8OD, but sat in the “too hard” basket, mostly because I was afraid of a difficult software task, which in the end would turn out to be rather simple.

“After quickly whipping up a test app which just gives it an IP address, ” Oh sure, I spent *days* getting to that point and I was wicked pleased when i could ping it!
Seriously though, that’s way more than half the battle. If you look at the first chunk of code here: https://olduino.wordpress.com/2014/12/11/minimal-http-server-with-w5500/ that could give you a “hello world” pretty quickly.
I had a similar conflict on the spi bus early on with an SD card. I found it wouldn’t release MISO even when it was deselected. I dealt with it on the olduino board by putting a 1K resistor between the arduino’s MOSI header and my internals. This was important because the 1802 Olduino also needs functioning SPI to boot. I think this was before the ethernet card so i never noticed the problem there.
