I *do* know it will take special layout considerations and the right settings. If anyone will figure it out, I'd bet DFI will do it first.
Based on what I've seen with my own eyes I'd say it's entirely possible that DDR400 1T could work with 4 sticks.
But let's just wait and see before anyone starts doubting it.
