Ideally you want to be avoiding the south bridge altogether.

A board like the Tyan S5396 has an MCH with 2 x 16 lane PCIe slots, so a 
high bandwidth storage controller can go in one slot and quad GigE or 
10GE in the other and both have direct access to CPUs/RAM.

These slots are also PCIe V2.0 capable, although I am not aware of any 
card that take advantage of this.
