    Hmmm....we've been using SysKonnect (older ones -- SK-9843 chipset)
    and have been pretty happy. These tend to have a lot more packet
    memory than most other cards (this means that interrupt coalescence
    can buy you more). Of course, these don't currently support
    polling..... :(

    Don't suppose you'd be willing to post your motherboard test results?
    We have found that SuperMicro motherboards (ServerWorks chipsets) are
    pretty good, but we don't have the resources to do exhaustive testing
    of all motherboards out there.
