Looking for a board that has integrated graphics as well as IOMMU/AMD-Vi

[Mardok]

I'm looking to build a system that will run Xen with Linux as the host and Windows as a guest.  I want to expose an integrated graphics card to the Linux host and use PCI-passthrough to expose my other GPU to the Windows guest.

I need a board that supports IOMMU/VT-Vi and has an integrated graphics card.

I looked around and these models fit the price range I'm looking for and have an integrated graphics card, but I don't know if they support IOMMU/AMD-Vi.
GIGABYTE GA-78LMT-USB3
GIGABYTE GA-78LMT-S2P
GIGABYTE GA-78LMT-S2
GIGABYTE GA-880GM-USB3

If none of these models support AMD's virtualization, do you know of a board that does?

I can only attest to the last one the 880 it does support amd virtualization. Have a friend i put that board in his build and turned it on for him in bios so i know it has it i havent used any of the others except the 78LMT-USB3 and i wasnt asked to turn it on and didnt look for it.
