I have already made one for the 2.4.20 kernel module and the 1.0.4 bridge-utils. Since I was making this for the Emulab testbed I also had to change the src/dst MACs that were going to the tap; otherwise, the underlying switch would drop the mirrored packets as their MAC's were not registered on the VLAN where the tap sat. If people have any interest in this I can share with the code.
