Can you be more specific? This is the same sort of thing people
normally say but the experience is that it rarely survives a successful
product.

It doesn't break down immediately; a combination of volume and the next
generation product coming along and grabbing attention is usually what
causes things to break down. However, if you're totally confident that
all the BIOS authors at the OEMs are going to work well together here
then I guess it's only Moorestown that's affected.
