I think you're looking for eldoc-mode. I've got this in my .emacs:
(mapc (lambda (mode-hook)
(add-hook mode-hook 'turn-on-eldoc-mode))
'(emacs-lisp-mode-hook lisp-interaction-mode-hook ielm-mode-hook))
In principle this is not limited to elisp, you can implement this
functionality for any language/major-mode, I did a toy implementation
for PHP once.
HTH,
Anselm
