Try a machine with a 64/66 PCI bus, or preferably,
a PCI-X bus that can run 64/100 or better.

I got line speed packet generation and reception on
a dual 2.8Ghz Xeon machine with PCI-X (64/100) bus and a dual
port Intel pro/1000 NIC.  I tested with 1500 byte packets
and transmitted and received 999Mbps of traffic between
two ports (total of ~4Gbps across the PCI backplane).

I wasn't routing or anything like that, but at least for
packet generation it worked fine.
