Geom_gbde and Hardware Crypto Accelerators - FreeBSD

After searching google and the archives I wasn't able to find any current information on the status of hardware cryptographic accelerators (like the Soekris vpn1401) and gbde. Can gbde harness the power of one of these accelerator cards yet? If so do they provide significant offloading from the processor(s)? Any comments on the Soekris vpn1401 card I've been thinking about? Thanks in advance. Dustin Wilhoit us...

    There is partial support for opencrypto/hifn/vpn1401 in the p4
    branch phk_gbde, but it doesn't help very much because of the high
    setup overhead of the hifn chip.
