It appears that the "preview" package adds its setup function to this  
hook when it is loaded, but it isn't loaded until after the hook is  
executed.  That's the design of AUCTeX, which will only work if you  
load the preview package prior to using LaTeX.

Try adding this:

(autoload 'preview-mode-setup "preview")

to your Preferences.el file.
