It's very easy.

This is the router I'm using here at home; SpamAssassin 2.20 + Exim 
4.05/4.10 + Courier-IMAP (wrapped for long lines):

# Spam Assassin
spamcheck_router:
   no_verify
   check_local_user
   # When to scan a message :
   #   -   it isn't already flagged as spam
   #   -   it isn't already scanned
   condition = "${if and { {!def:h_X-Spam-Flag:} {!eq \
            ${received_protocol}{spam-scanned}}} {1}{0}}"
   driver = accept
   transport = spamcheck

And this is the transport, also wrapped for long lines:

# Spam Assassin
spamcheck:
   driver = pipe
   command = /usr/exim/bin/exim -oMr spam-scanned -bS
   use_bsmtp = true
   transport_filter = /usr/bin/spamc
   home_directory = "/tmp"
   current_directory = "/tmp"
   # must use a privileged user to set $received_protocol on the way back
   # in!
   user = mail
   group = mail
   log_output = true
   return_fail_output = true
   return_path_add = false
   message_prefix =
   message_suffix =

Don't forget to things like "command =", "user =" and "group =" to be 
consistent for your mail server, otherwise things will break 
spectacularly. :)

Oh, and don't fret much about the fact that I'm using Courier-IMAP 
rather than Cyrus for the 2 stanzas above; in the grand scheme of things 
it's not gonna make one iota of a difference.

If I checked all messages for "spamminess" at SMTP time my lusers would
drag me out and hang me.

I run SpamAssassin at delivery time so that I can have it only scan for 
spam for certain users.

Debian Linux, of course :)
