it would be cool if you could re-rout that 'off' setting to a number (say level 24, if you're not using it much).
Have you tried changing one of the level values to 'device 0' or '-1'?
If it would work, the system would send a negative voltage to the leds, which only allow current flow to flow in the positive direction, so they should block the light.
Also noteable, that the kindle does the light in 8 bits, or 256 intensities. So far they only use 254 on yours. Perhaps you can get it to work brighter than the stock settings by modifying the values!
