Put the following in ~/.emacs or ~/.gnus.el: 

  (require 'gnus-sum)
  ;; (setq gnus-summary-line-format
  ;;   "%«test%» %U%R%z%I%(%[%4L: %-23,23f%]%) %s\n")
  (setq gnus-summary-line-format
        (concat "%«test%» " gnus-summary-line-format))
  (setq gnus-balloon-face-0 'rs-gnus-balloon-0)
  (defun rs-gnus-balloon-0 (window object position)
    "Hello") ;; [1]

When entering a summary buffer in Gnus, you'll see the following:

,----[ *Summary buffer* | Emacs 2008-03-14 | Current behavior ]
| *test* O  [  22: Jason Rumney           ] Re: --script
| *test* O  [  26: Andreas Schwab         ] Re: Emacs Bazaar repository
`----

The `*' shouldn't be there.  Additionally, when moving the mouse over
the text "test", `rs-gnus-balloon-0' should be called and the
help-echo should display "Hello".  Currently, nothing happens when
moving the mouse over "*test*".

I get the expected behavior when running an older binary (2008-03-08
19:12 CET) with the same (Gnus) lisp files, same settings, etc.

Bye, Reiner.

[1] In my real setup, it displays something more useful than "Hello". ;-)
