Radio Baily has posted a fix for the PowerBook/10.3.8 screen brightness bug:

One of the nicest features of the 15″ Aluminum PowerBooks (and some of its siblings) is their ambient light sensors. Situated under each speaker grille, these allow the ‘Book to tell how bright its environment is and adjust the screen brightness (and backlit keyboard if you have one) to suit.
It’s a thing o’ beauty to put the machine to sleep in a full light office, wake it up in a low light environment at home and have the screen dim to a comfortable level and fade up the keyboard lighting. That was until 10.3.8 when things went slightly batty. The PowerBook developed a nervous tic. You could almost sneeze and it would drop the brightness down a bit then back up again, resulting in a maddening flicker effect.
Until Apple fixes it here’s how I fixed it on mine.

Beware though, it’s not for the weak of heart.
