It turns out that the ebu, in the gpio_led structure, uses gpio starting from 32, so defining "fake" leds using gpios 32-40 I could map all missing leds. Since they're active low, I used lq_register_gpio_ebu(0xff), so they all turn off as soon as the kernel calls lq_register_gpio_ebu (contrary to leds controlled by "real" gpio, they're lit at power on, the original firmware turns them off very soon).
