My (capacitive) media keys have recently become autonomous, causing my wifi to switch on and off at random intervals and effectively rendering the machine unusable.

How can I disable those keys? My preferred solution is to simply disable or misconfigure the daemon that intercepts the XF86WLAN and XF86Bluetooth keycodes. I can't seem to figure out though which daemon is currently responsible for this, so some help is appreciated.

I'm running Debian Wheezy with a default GNOME 3 setup.
