I'm pretty sure no-one will read this now, but:
I was in a hurry to write a comment before I hit my 2 hour cutoff, so didn't even read the article properly. I was under the impression - albeit very briefly - that this thing was PCI. Amithlon and Mediator PCI addressing ranges are different, so it wouldn't be a simple matter of adapting for the Amithlon.
Anyway, I was wrong. It's not even PCI. I'm an idiot. Don't read the comment ;-)
