Magento

I try to disable some modules output in the system/configuration/advanced and its not working. I try for the Default config , main website and
default store view.

Them in app/etc/modules/Mage_All.xml i change the modules to false and it work, but some module require other and give errors in some pages.

For example Mage_GiftMessage to false give me errors in

- dashboard
Warning: include(Mage/Giftmessage/Model/Entity/Attribute/Backend/Boolean/Config.php) [function.include]: failed to open stream: No such file or directory in DEMO/app/code/core/Mage/Core/functions.php on line 44

- edit product
Warning: include(Mage/Giftmessage/Model/Entity/Attribute/Backend/Boolean/Config.php) [function.include]: failed to open stream: No such file or directory in DEMO/app/code/core/Mage/Core/functions.php on line 44

It is a bug ????

I want to disable or hide them from the user interface without having to change the template layout.
