The same is true on Nexus 7 which uses /sys/class/leds/lcd-backlight (hmm, pattern!)
NOTE: This script is designed for Laptops. I'll prepare a second version later once I work on some extra tooling and have more questions to ask about the mobile world with Android kernel.

Somebody might regard the uname -a reported hostname (which by default on most systems includes a username) as sensible.
This could do it:
uname -a |sed s/uname -n/fake-host/g
Oh, good point about the hostname! I didn't realize that.
I'll change how uname gets invoked so that we don't have this needless piece of info. I'm currently working on a much much better (though far more complex) version that can do some useful manual tests as well. I'll post it to the main tree at github.com/zyga/lantern.
In the meantime, you can open issues on the current version of the script there.
This doesn't seem to work on the BQ phone. All the interesting values there are in
/sys/class/leds/lcd-backlight. Awww, android, how I hate thee!
