This works for me:

#+begin_src emacs-lisp
 (setq ibuffer-saved-filter-groups
       (quote (("default"
                ("lower" (name . "\\`[^[:upper:]]*\\'"))
                ("Upper" (name . "[[:upper:]]"))))))
 (add-hook 'ibuffer-mode-hook
          (lambda ()
            (setq-local case-fold-search nil)
            (ibuffer-switch-to-saved-filter-groups "default")))
#+end_src

"[[:lower:]]" would match names containing at least one lowercase
letter.  That's not what you want.  The regexp used above for "lower"
matches any string not containing any uppercase letter.
