I tried xev and found out the keypress is actually reported:

KeyPress event, serial 30, synthetic NO, window 0x3800001,
    root 0xb5, subw 0x0, time 3808064705, (231,286), root:(235,359),
    state 0x0, keycode 242 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 33, synthetic NO, window 0x3800001,
    root 0xb5, subw 0x0, time 3808064829, (231,286), root:(235,359),
    state 0x0, keycode 242 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:

So, I believe my GNOME installation handles this. That means that if
You don't use DE that manages that for You, You can have xbindkey run
a script deactivating device wia xinput.
