''it doesn't go very well''

What, exactly, do you mean by that?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I doesn't get any sign of life from it...

So maybe the SPI isn't set up properly or maybe it's just me that haven't ported it correctly.

I've uploaded the code - keep in mind that it is a mix of my fully working LCD library/interface which I use for debugging, and the not working ported W5100 code!

Have you checked with a scope that the clock is being generated?

And any required chip select?

And data on the data lines?
