I just tested this, on another MWE:

--8<---------------cut here---------------start------------->8---
;;; .emacs-minimal.el --- Test file

;;; Commentary:

;;; Code:

(defun try-require (feature)
  "Attempt to load a FEATURE (or library).
Return true if the library given as argument is successfully loaded.  If
not, just print a message."
  (condition-case err
      (progn (if (stringp feature)
                 (load-library feature)
               (require feature)) t)
    (file-error (message "Requiring `%s'... missing" feature) nil)))

(when (require 'idle-require nil t)
  (setq idle-require-idle-delay 5)
  (setq idle-require-load-break 2))

(when (try-require 'idle-require)
  (setq idle-require-idle-delay 5)
  (setq idle-require-load-break 2))

(provide '.emacs-minimal)

;; This is for the sake of Emacs.
;; Local Variables:
;; flycheck-emacs-lisp-initialize-packages: t
;; flyspell-mode: nil
;; End:

;;; .emacs-minimal.el ends here
--8<---------------cut here---------------end--------------->8---

See the results on

- I still have the variables from the package `idle-require' reported as

- while that's a package which is under ELPA (right now in
  ~/.emacs.d/elpa/idle-require-20090716.3/) and I do have
  `flycheck-emacs-lisp-initialize-packages' set to `t'.

Best regards,

PS- A funny thing (?) is that only the first occurrence of the variable
    is reported as unknown.
