Perhaps Lab Tick, i don't have an MBP so don't know how well it works.
There's just a circle with a line going through it indicating, "You can't turn on the backlit keys right now, peasant boy! Only when the sun goes down a bit shall I let you fiddle with my backlit keys!"
I have a MacBook Pro, and I have found a manual, maybe rather unorthodox way of overriding the automatic keyboard illumination. Heres how it goes:
1. If you have a MacBook Pro, place your hands over both of the speakers, where the light sensors are located. Notice that the screen dims and the illumination turns on.
2. Quickly remove one of your hands [preferably the side where there is the least light] and press the keyboard illumination key (keep it pressed), in my case F6.
3. Remove your other hand as well. Now you can stop pressing the illumination button, and your keyboard should be lit.
The computer will however not allow you to adjust the level of illumination or even turn it off... therefore you just have to cover the speakers again, so that there is a change in light level and remove them again... the backlight will then switch off.
Hope it helps...
