Have you looked at other PowerBooks in the same environment? Could it  
be a problem with your particular machine?

Assuming it isn't, why not fiddle with Mac OS X accessibility options?  
Enhanced contrast or white-on-black might help.

Here's a more theoretical idea: Polarized glasses.

With the correct polarization, polarized glasses would block much of  
the ambient light, while allowing the LCD screen light to pass  
unimpeded. The problem is that polarized sunglasses are commonly made  
for drivers, and they are designed to block horizontal light. LCD  
displays these days are no longer made with horizontal polarization,  
yet usually they have angles smaller than 45deg, which means they would  
be blocked to a greater or lesser degree by such sunglasses. Maybe some  
intrepid soul has already come up with a pair of glasses with the  
correct polarization. Or perhaps you can cut your own clip-ons -- or  
even try cellophane
