https://fedoraproject.org/wiki/Input_device_configuration, search for
"remove key".

Just FYI, the log says about those two sections:
    (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or
    'vmmouse' will be disabled.

You can just remove them, they don't really serve a purpose in your setup.

DontZap is the default since IIRC 1.6.1, not needed unless you want to
disable it extra-hard :)
