I've now got the following in .emacs:

(setq-default fill-column 70)
(add-hook 'text-mode-hook 'turn-on-auto-fill)
;(add-hook 'latex-mode-hook 'turn-on-auto-fill)
(add-hook 'html-mode-hook 'turn-off-auto-fill)
(add-hook 'latex-mode-hook (lambda() (set-fill-column 100)))
(add-hook 'mail-mode-hook (lambda() (set-fill-column 60)))

When I C-x C-f foo.txt and use C-h v to check fill-column, it says 75 (the 
built-in default, I think)!. When I C-x C-f foo.tex, it's still 75. When I 
C-x m, it changes to 60.

I think my Emacs must be behaving differently from yours! Is that possible?
