    It sounds like a PCI initialization issue with that card, which is not
    surprising considering that it is a broadcom.  An NMI pretty much either
    means that the system ram is bad (which is not likely here), or that a
    PCI card with shared or internal local memory has been misconfigured.

    Someone would need to check the FreeBSD broadcom driver for changes 
    that might have gone in to support the card that we don't have.
