I can confirm that FreeBSD 7.0-RC1 can route packets at 1gbps.  I used a
late-model Supermicro Xeon server which has two gigabit NICs on a
PCI-express "4x" lane.

With the new em driver improvements in 7 it uses very little CPU time, I
would recommend using Pro/1000 on 7.0 with a decent server motherboard
if you want to achieve this speed.
