No dice. :-/ I played around with some of my own changes that did the same thing, as well as your patch, and I always get nothing on the receiver.
What next? try an x86 box and make sure it works with that? Is there something In the ymfpci driver I should look at? (also, are there any IRC channels you or someone else that knows about iec958 would be on?) Thanks!

Charles Shultz had the best answer: "Why do musicians compose symphonies and poets write poems? They do it because life wouldn't have any meaning for them if they didn't. That's why I draw cartoons.
