Some people add their contact details to the screensaver images, so if you lose your kindle your contact details are the first thing someone who finds it will see.
Maybe a better hack would be to disable screensavers since they serve no purpose on an e-paper display and actually cost battery to switch from text -> screensaver -> text.
The better behavior would be to not flip the screen at all and keep it static, using no battery.
