You might be able to use the DAG cards from Endace Measurement Systems:

They have drivers for Linux (and FreeBSD ones are either available or under development); the current CVS version of libpcap supports passive capturing on DAG cards, and tcpdump, Ethereal/Tethereal, etc. can just use that version of libpcap. (The current version of Ethereal won't show the DAG devices in the drop-down list in the capture window - we need to convert Ethereal to use the new libpcap API for getting a list of capture devices, if the version of libpcap being used has that API; that's fairly straightforward if you're building Ethereal from source on UNIX, but it's a bit more of a pain on Windows, where we'd want the Ethereal binary to work with WinPcap 2.x and 3.x.)
