NIC-performance degradation -- or (apparently) security holes
Well, the security thing is a hardware limitation. You'll have to wait for next-gen hardware to support VT-d (I think all of motherboard, processor and PCI cards, though I may be wrong about this). There is some experimental support for VT-d in the latest Xen, but not in RHEL 5.
