Dreamer: The ram expansion is REAL it is coming. The reason i know is because i have it. The one i have is not 256 but 128MB+ internal 64MB.
It just may take time. For all Audya 76 owners like me, the soundboard is missing the pins to attach the ram expansion into. The soundboard can either be swapped out for an Audya 5 sound board (u will lose one of the digital ins or outs i forget at this moment) or u can solder in the pins- the holes are there it just needs the pins.

But it does exsist.
