Steps:
1) Connect to your Kindle via USB
2) Create a file in the root directory called "TESTD_PREVENT_SCREENSAVER" - can be an empty file, but must be named exactly. (It'll ultimately sit in /mnt/us/ )
3) Reboot the device

Note I am not entirely sure what other consequences this may have, so use at your own risk - from what I can tell, this should be relatively safe.
That's a great finding, however, after testing it for a while I concluded that even the magnetic case doesn't put the device into sleep mode (apparently it only turns off the backlight), which results in a relatively quick battery draining.
For me the ideal solution would be to extend the timeout from 10 minutes to some larger value (or a very large value to simulate infinity). Do you perhaps have any idea how to change this value? I have a jaibroken PW5.
