Well, we have SB600 supported already, SB7xx/SB8xx should be fairly compatible. Only 850 has PCIe.

None of these have USB, but this isn't on your list anyway

AMD SB chips are dirt cheap (they sit on motherboards costing less than 100USD, after all). Supply might be running low, though.

I honestly see NO problem using an SB850.

Edit: I forgot about 950, but I don't see any advantages, it's using a faster A-Link Express 3 (probably PCIe 3.0) but has no extra features and many bugs.

This weeks pet peeve:
Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

While we have the issue that "it hasn't been tried yet", as mentioned by Olegil, my choices would be either A70M or A75. These are "Fusion Hub Controller" chips rather than "Southbridge" chips, but from my point of view that is essentially the same thing.

Some reasons for this:
These are relatively easy to get documentation for from AMD's Embedded Developer Suport program website. (both PCB type stuff and driver coding type stuff)
These are the most advanced ones at the Embedded Developer site, last time I checked there. (They have USB3)
They are relatively inexpensive, and have in the past been easy to buy at Avnet in small quantities. (I haven't looked recently)
As embedded support prodducts, they may be around longer than some desktop or laptop target devices.

I had once tried to obtain documentation for Intel's Platform Controller Hub chip, essentially the same thing as AMD's Fusion ontroller Hub, but was not granted access to any of that. I had applied through Intel's Embedded developer program, which seems similar to AMD's program.

For FPGAs, there are several pieces of things available, such as from opencores.org and other places. I'm not aware of a readily available open PCIe interface core to connect to CPU. Some things, such as SATA and HD-Audio were not available there, I eventually found something about them, but they may not be license compatible to go into a single chip together. A couple pieces that I would have wanted may have only been "for academic use only", but not for use in commercial products. I forget what as it has been a while. And an FPGA would likely consume more power than an FCH/Southbridge chip, but might give more flexibility if you can afford the power.

I don´t understand your question.
If you use a new PPc SOC like the T1020/40 you can use 4x PCIe for the graphic card and x1 PCIE for SATA / SOUND / USB3.0.
There are 2 SATA Ports on the T1040, but I think it is better to use a PCIE -> Sata card , because it is faster and it frees an additional PCIe 1x Port.
