I'm not sure how well HVM PCI-passthrough works with Xen 3.2 and how 
useful or functional it is. Keir Fraser states that it's "Basic code" but 
"pieces are still missing":

        http://xen.org/files/xensummit_fall07/02_KeirFraser.pdf

I think it's Intel VT-d only as AMD's IOMMU platform will not be available 
before 2009.

Best regards, Mark
