Whilst I agree that it is highly unlikely that any of the Mobo manufacturers will foot the bill for this fiasco, it is of their making and they should have the decency to own up to their mistakes. (tries to stifle loud laughter at this happening) The reality is, however, that this is probably a lame duck to start with. None of the Mobo manufacturer's will admit there is a problem with the 9128 chip and as there is always built in obsolescence to any electrical product this is something that they know will just fade away given time.
If the chips are user replaceable (which I doubt) then they should be offered at a heavily discounted price, ( possibly on proof of purchase of a board with the 9128 chip) at least in recognition of the fact that they are responsible, with clear instructions on how to implement the replacement without voiding any remaining warranty that the user has.
