I'm back on this, trying to do it properly. I've removed by mod to mm-plugin.c, and added a udev tag 

G_MODULE_EXPORT MMPlugin *
mm_plugin_create (void)
{
    static const gchar *subsystems[] = { "tty", "net", "usb", NULL };
    static const gchar *vendor_strings[] = { "cinterion", "siemens", NULL };
    static const guint16 vendor_ids[] = { 0x1e2d, 0x0681, 0 };
    static const gchar *drivers[] = { "linmux", NULL };
    static const MMAsyncMethod custom_init = {
        .async  = G_CALLBACK (cinterion_custom_init),
        .finish = G_CALLBACK (cinterion_custom_init_finish),
    };
    static const gchar *udev_tags[] = {
        "ID_MM_CINT_LINMUX",
        NULL
    };

    return MM_PLUGIN (
        g_object_new (MM_TYPE_PLUGIN_CINTERION,
                      MM_PLUGIN_NAME,                   "Cinterion",
                      MM_PLUGIN_ALLOWED_SUBSYSTEMS,     subsystems,
                  MM_PLUGIN_ALLOWED_UDEV_TAGS,  udev_tags,
                      MM_PLUGIN_ALLOWED_VENDOR_STRINGS, vendor_strings,
                      MM_PLUGIN_ALLOWED_VENDOR_IDS,     vendor_ids,
                      MM_PLUGIN_ALLOWED_DRIVERS,        drivers,
                      MM_PLUGIN_ALLOWED_AT,             TRUE,
                      MM_PLUGIN_ALLOWED_QMI,            TRUE,
                      MM_PLUGIN_CUSTOM_INIT,            &custom_init,
                      NULL));
}

i.e. I've left in, for now, the MM_PLUGIN_ALLOWED_DRIVERS/drivers additions.
ENV{ID_MM_CINT_LINMUX}="1" is added to the udev rules, and everything reloaded.
Which puts me back to getting
[src/mm-plugin.c:251] apply_pre_probing_filters(): (Cinterion) [ttyMux1] filtered as couldn't retrieve drivers
What would be the neatest way to address this?
