I have tried it on the ding-rn-digest list an it worked just fine. A
cookbook recipe:
 * Get procmail: ftp://ftp.informatik.rwth-aachen.de/pub/packages/procmail/
 * Follow the installation procedure and note the subtleties involved
   with older versions of sendmail.
 * use a '.procmailrc' with something like:

---8<---
PATH=$HOME/bin:$HOME/Abin:/usr/bin:/usr/ucb:/bin:/usr/local/bin:.
MAILDIR=$HOME/spool	# You'd better make sure it exists
DEFAULT=$MAILDIR/mbox.spool
LOGFILE=$MAILDIR/from
LOCKFILE=$HOME/.lockmail

# An alternative and probably more efficient solution to splitting up a digest
# would be (only works for standard format mailbox files though):
:0:
* ^Subject:.*Digest
|formail +1 -ds cat >>mbox.spool

# Anything that has not been delivered by now will go to $DEFAULT
# using LOCKFILE=$DEFAULT$LOCKEXT
---8<---

The procmail package contains some more elaborate rules examples.

Of course you will have to add 
(setq nnmail-use-procmail t              
      nnmail-procmail-directory (expand-file-name "~/spool/")
      nnmail-resplit-incoming t)
to your '.gnus'.
