Can you use a very strong fronglight to see if this is actually the case? 
(Illumination angle may be important as well.)  The state of the liquid 
crystal polarizing switches should be visible under sufficient 
illumination, and whether they change with input would be pretty 
definitive.
I actually used to operate my iBook G4 in "frontlight mode" in bright 
sunlight for a while (until the wifi card flaked out, tying it to my 
desk).
