I agree that the problem should be solved but just in case Colleen wants
to continue with his installation (I know, he is installing Gentoo for
the first time so I doubt he values his time very high ;-) ), I suggest
he either implements my proposal outlined above or adds similar code to
/etc/conf.d/net:

preup() {
    if [ "$IFACE" = eth0 ]; then
        ebegin "Reloading broadcom and tg3 modules"
        modprobe -r foo bar &&
        modprobe broadcom &&
        modprobe tg3
        ewend $? "Failed to reload modules"
    fi
    return 0
}
