"Disable module output" is a configuration, stored in the database, so you cannot change it from files, but with access to the database (MySQL console, phpMyAdmin, ...) you can undo it for all modules with the following query:

DELETE FROM core_config_data WHERE path LIKE 'advanced/modules_disable_output/%'

or for only core modules:

DELETE FROM core_config_data WHERE path LIKE 'advanced/modules_disable_output/Mage_%'

or for a specific module (in this example Mage_Customer):

DELETE FROM core_config_data WHERE path = 'advanced/modules_disable_output/Mage_Customer'

Magento – What Default Modules I can disable

I can add to that:

Mage_GiftMessage - seams it's not disableable in 1.8
Mage_XmlConnect - if you don't have / need a mobile app.
Mage_Authorizenet
Mage_Paypal (if not used as a payment method)
Mage_Paygate (Only if you disable Mage_Paypal, Mage_PaypalUk and Mage_Authorizenet)
Mage_Weee (only if you disable Mage_XmlConnect also)
Mage_Usa - only in ce-1.8.1.0. (see below why)
Mage_GoogleCheckout - can only be disabled in ce-1.8.1.0 and only if you disable Mage_Usa. It doesn't work for previous versions because of this http://www.magentocommerce.com/bug-tracking/issue/?issue=14359
Mage_Oauth - if you don't need the REST API
Mage_Api
Mage_Api2 - only if you disable the Mage_Oauth also.

As a general rule, you can disable (almost) any module, but you have to check in app/etc/modules/*.xml if there are any other modules depending on the module you want to disable. If there aren't any you can do it. If there are you must disable those also.

As an exception from the general rule, there are some modules that can break the admin if you disabled them because of the way Magento 1.x is build. the Mage_Adminhtml module contains references to the other modules (like customer, sales, ...). Looks like In Magento 2.0 this will be changed.

Difference Between Disable Module Output and Module Active in Magento 1.9

System > Configuration > Advanced > Disable Modules Output will not actually disable that module. It work as the name suggest, disable modules output.

When you look at

abstract class Mage_Core_Block_Abstract

final public function toHtml()
{
    Mage::dispatchEvent('core_block_abstract_to_html_before', array('block' => $this));
    if (Mage::getStoreConfig('advanced/modules_disable_output/' . $this->getModuleName())) {
        return '';
    } 

// It is checking If its in disabled mode then just return blank output
.......
}

While app/etc/modules completely disabled module
