Xen supports PCI device passthrough to paravirtualized domUs without any
additional hardware support/requirements.

PCI device passthrough to HVM domains requires VT-d (iommu) support.

VT-d support is in the chipset. Not many chipsets have it yet.. And there
are bugs in the VT-d support in many motherboards..

Yes, I think Xen 3.4.1 has VT-d support. Although the code is still not very
mature, especially with graphics cards there are a lot of problems. 

See xen-devel and xen-users archives for more information.
