is it enough to mark all long lines? Then hi-lock-mode might help
you. Try the following:
(highlight-regexp "^.\\{81,\\}$")

That, too, can be done with the new whitespace-mode:

(let ((whitespace-line-column 80) ;80 is the default
(whitespace-style '(lines-tail))) ;or '(lines) for the whole line
(whitespace-mode 1))
