Try adding "noise_generator 1" to the offending textures.

POV-Ray 3.7 beta 39 (and probably also earlier betas) had a bug causing 
the noise_generator to default to 1 instead of 2 for patterns used 
directly in a texture{} statement (which typically occurs in combination 
with a texture_map). This caused a change in overall "brightness" of the 
pattern. As this was fixed with beta 40, your observation may well be a 
result of this change.

If that is the case, then beta 40 is right and 39 was wrong, and the 
easiest way to fix your scene is probably to explicitly specify 
"noise_generator 1" wherever you are using a texture_map.

See http://bugs.povray.org/task/168 for a few more details.
