Great news :)
If I understand well (my English knowledge is not so good, and my electronic 
one is even worse) , you are thinking that Envy24HT-S is similar by design 
with the Envy24MT ? The only thing to do is to find the wiring between the 
envy chip and the codec chip ? This can be done with a ohmmeter.

I don't understand exactly what do you call "reference design", but the 
Chaintech and Onkyo board doesn't look very similar to me.

For now, I do not have a SE-90. I will not spend 110€ in an audio card if 
there aren't good chance for it to be supported by my OS of choice.
On the other hand, if you tell me that this card could to be supported "for 
almost sure", I could buy it.
