I suppose that these warnings are due to

        case OPTV_STRING:
            if (*s == '\0') {
                if (markUsed) {
                    xf86DrvMsg(scrnIndex, X_WARNING,
                               "Option \"%s\" requires a string value\n",
                               p->name);
                }
                p->found = FALSE;
            }
