This is the code I was referring to, in iTCO_wdt_start:

        /* disable chipset's NO_REBOOT bit */
        if (iTCO_wdt_unset_NO_REBOOT_bit()) {
                spin_unlock(&iTCO_wdt_private.io_lock);
                pr_err("failed to reset NO_REBOOT flag, reboot disabled by hardware/BIOS\n");
                return -EIO;
        }
