Pretty cool -- I'd love to see a walkthrough/narrative of what you've done (that is to say, once you've arrived where you want to) to get fpgaminer up and running on the ML605. I'd be keen on picking up one of those boards to muck around with, but would be a little more confident with a primer.
Double that!
@Epicblood: Please post any relevant links to where we can get the parts needed to follow you on this project! Apicture or two of you current setup would also help.
