The series 5.x firmware is using upstart.
Models prior to that used SYS-V.

I think you have it, that screen is the default screen when upstart doesn't have anything else to do (either before start-up or after shut-down).

Since the Kindle (normally) **never** shuts down - they probably don't see any reason to change it.

For other readers:
The Kindle's main processor does a "suspend to RAM" and then the RAM is powered down into a "keep alive" mode.
Another note: The above is not strictly related to when it shows a screen saver, it can and sometimes will, suspend between page turns.
