PCI Passthrough/AMD-VI on AMD A85X chipset

Greetings, all! New poster here with a bit of a head scratcher, for myself at least. I am looking into building a home server for some personal tinkering, specifically a virtualization server, probably to experiment with VMware ESX, Hyper-V, or Xen. One feature I was hoping to experiment with was PCI passthrough, or AMD-VI as AMD calls it. I was looking to go with AMD since their processors that do PCI passthrough seem to be substantially cheaper than the select Intel ones that have that functionality (VT-d). I looked into using an AM3+ socketed processor, but I am looking to keep it small, using either a micro ATX or mini ITX motherboard, which apparently aren't made with an AMD 900 series chipset. That leaves the FM2 socket, with it's higher end A85X chipset. I searched some of the pdfs on AMD's support page, and did as extensive a web search as I could, but all I can find is that the A85X chipset supports IOMMU v2. However, there's no mention of AM-VI, which is what I assume would mean PCI passthrough.

So, to summarize, my questions are this: Does the A85X chipset support PCI passthrough/AMD-VI? If not, what does IOMMU v2 refer to, some functionality referring specifically to virtualizing the GPU component?

Thank you for any advice you can provide.
