No changes in kern.log after pressing the bezel buttons.
Nothing happening but also no crazy stuff going on after:
sudo /lib/udev/keymap -i input/event5
No effect after:
sleep 1; sudo /lib/udev/keymap -i input/event5
EDIT: I am not sure if this is what we are looking for, I guess this is still just entering a new line after the other all over again but with no additional crazy stuff going on:
sleep 1; sudo /lib/udev/keymap -i input/event4
