Sorry, but you have to divide by 255  (not 256).
Pure White is 255, and in pov it's 1.

Unless the ambient is 1 (which is not the default), 
the texture will only reflect part of the light it get,
multiplying by the pigment

(a reflected <1,1,1> would get out as desired, but it rarely 
happen)

Moreover, there is a gamma correction applied to the pov-output.
The default gamma is 2.2 (unless, like me, you have a custom built
pov so as to get a default gamma of 1, 
but then you wouldn't have posted here)
