Apparently Micron is no longer working on Mamba and their other chipsets. A friend of mine (I don't want to get him in trouble so no names), has informed me that they have sold their dual DDR channel chipset to Intel . One interesting tidbit from IDF this week , ever wonder why Nvidia doesn't have a FSB license from Intel? It's because Intel has plans to introduce Dual channel DDR into their servers . Micron was denied a FSB license for the exact same reason , and we should see the Northbridge from Micron's chipset work in the near future from Intel
