Is the bcm5700 module provided by the stock Linux kernel?  I only see one
reference to that string in the source tree for 2.4.18 (which is probably
related to code which converts vendor ID's into names for /proc/pci, but
that's just a guess):

    [mct@antarctica /usr/local/src/linux-2.4.18]$ grep -rli bcm5700 .
    ./drivers/pci/pci.ids
    [mct@antarctica /usr/local/src/linux-2.4.18]$

In any case, could it be that the full_duplex configuration parameter is
really an array of booleans, the first element of which configures the
first card found, the second element of which configures the second card
found, etc?  I know that's how the tulip module is configured, as an
example, and as is indicated in the "modinfo -p" output:

    [mct@heartofgold ~]$ modinfo -p tulip
    [...]
    full_duplex int array (min = 1, max = 8)
