NForce4, quad Opteron, 2200 and three 2050 allows four 16 lane cards.
Forum posts say Tyan is almost done designing a MB for that config.

There is another config of NVidia 2200/2050 for 16 cards but I don't
know if anyone is building it.

But these configs are coming in the future and we should plan for them.
