Finally I got a novcache:

,----[ gnus.el ]
| ;;; Experimental Gnus setup
|
| (setq gnus-select-method '(nntp "news.gmane.org"))
| (setq gnus-secondary-select-methods
|       '((nnimap "localhost"
| 		(nnimap-address "localhost")
| 		(nnimap-server-port 993)
| 		(nnimap-stream ssl))))
|
| (setq nnimap-nov-is-evil nil)
| (setq gnus-cache-enter-articles '(ticked dormant unread read))
|
| (setq org-gnus-nnimap-query-article-no-from-file t)
`----

Now the strange thing is that the novcache file in ~/News/overview is
100% identical to .overview in ~/News/agent

,----
| dmaus@t41 ~/News % md5sum overview/nnimap/localhost/INBOX/1280089306/novcache agent/nnimap/localhost/INBOX/.overview
| b4a78e25a064f0c260f76080a00991cd  overview/nnimap/localhost/INBOX/1280089306/novcache
| b4a78e25a064f0c260f76080a00991cd  agent/nnimap/localhost/INBOX/.overview
| dmaus@t41 ~/News %
`----

Anyway: `nnimap-retrieve-headers-from-file' does not work as expected.
First, it requires the group parameter without backend and server
prefix (e.g. "INBOX" instead of "nnimap+localhost:INBOX".

Second it would return a cons (min-UID . max-UID).  That wouldn't help
us, would it?

Third and amazingly my novcache seems to be corrupt right after
creation: `nnimap-retrieve-headers-from-file' does not get the maximum
UID but reads "INBOX" (?!) -- A string that looks kind of a header
information for nov -- and not "18753" what is the highest UID in the
mailbox.

Last line of the cache:
(it's a local copy of wanderlust general newsgroup accessed via IMAP)
