Is it just me or does the phone not have a keyboard back light? I have tried going into a pitch black room and it won't come on, I have also gone into every setting and found nothing about it, pretty dumb if it doesn't have one.
As far as I can tell, the backlight is "smart" and making use of the same sensor that prevents cheek dialing while you're on the phone. If your backlight goes off, shield that sensor and watch it come back on.
I was wearing a bright white t-shirt with the phone brightness up in a dark room, and that was enough to turn the darn thing off, so I'd say "smart" is not the word I'd use. I wish the sensitivity were user adjustable.

I've noticed the sensor is pretty sensative too. Also the backlight does go off without use. Not sure what the limit is, but I know when the screen dims before going off completely is around when they backlight goes off. Just tap the screen and it comes back or start typing again. Seems like they are trying to wring every bit of battery life they can.
The keyboard on my Ally was notorious for this, would be on when there is plenty of lighting, and would be off if I was laying in my bed at night in the dark texting someone. The one on my D3 seems to be a lot better, it usually is on if the room is dark, but it seems to time out pretty quick and shut off.
There is a light sensor involved for certain, and I wouldn't be surprised if an inactivity timer was in the logic as well.
To test the light sensor, just slide out the keyboard, and cover the entire black area where the earpiece, LED, and FFC reside. It will turn on and off on command.
It does seem a little sensitive as I've watched it turn off sometimes, but I was able to still see the keyboard so that was probably just the sensor working as it should, to save battery life. Just a change from what I'm used to, no big deal.
Yea it's been like that since my Droid and found it weird that it wasn't working...i also noticed that the vibrate on it doesn't even work at times so i think i have a semi DOA Droid 3.
