The Help is probably elder then the ELisp code. Look here:  
/Applications/Aquamacs  
Emacs.app/Contents/Resources/site-lisp/edit-modes/preview/

You make AUCTeX take regime over all TeX files you need to enable it:

	(add-hook 'LaTeX-mode-hook 'turn-on-reftex)   ; with AUCTeX LaTeX mode
	(add-hook 'LaTeX-mode-hook '(lambda () (TeX-fold-mode 1)))

and again you need to load a bit: (require 'tex-site). And here can be  
one problem: I think this file needs so customisation for its locality.

I don't know what might be going wrong. I hope you did the installation  
of AUCTeX and preview-latex according to the documentation and let make  
do it ... You can put into site-start.el or .emacs or into *scratch*  
with eval-region when you need it this little bit of code:

	(defadvice load (before debug-log activate)
	  (message "(Tipp von Kai G):Loading now: %s" (ad-get-arg 0)))

This will record in *Messages* which files get loaded. For me, when I  
first load a TeX source, this gets recorded:

	/Library/Application Support/Emacs/site-start.el
	(Tipp von Kai G):Lade jetzt: preview-latex.el

You see that it isn't 'my' installation that gets used ...

As mentioned above AUCTeX needs the (require 'tex-site) first and then  
the statements to make it take over over elder ELisp software. Upon  
correct installation these files and directories will appear in the  
install directory:

	drwxr-xr-x   6 root  admin     204 29 Sep 20:44 preview
	-rw-r--r--   1 root  admin     324 29 Sep 20:44 auctex.el
	drwxr-xr-x  43 root  admin    1462 29 Sep 20:44 auctex
	-rw-r--r--   1 root  admin   12421 29 Sep 20:44 tex-site.el

For my Emacsen I added this code make them be aware of all new places:

       (setq load-path
           (mapcar 'expand-file-name
               (append '(
                 "/Library/Application Support/Emacs"
                 "/Library/Application Support/Emacs/reftex"
                 "/Library/Application Support/Emacs/auctex"
                 "/Library/Application Support/Emacs/auctex/images"
                 "/Library/Application Support/Emacs/preview")
         load-path)))

Can you describe how you installed AUCTeX and preview-latex and which  
versions they are? There are also TeX files that are being installed  
into the TeX installation (the preview package, as available from CTAN.

What you're describing here is something that you added to your  
Emacsen's start-up code. Maybe the other code never got into Emacs. You  
can check success of additions to load-path by checking the value of  
load-path in Emacs (C-h v load-path <RET>) ...
