No special patches are required for Exim 4.x to deliver to Cyrus via the
"deliver" program, or via LMTP over TCP sockets.
As of Exim 4.12, delivering to Cyrus via a unix socket (using the LMTP
protocol) is supported.
Exim 3.3x has similar capabilities.

The Cyrus documentation isn't as archaic as you think, just
sendmail-specific, as that's what CMU (the people who wrote Cyrus) use
as their MTA.
The Debian package for Cyrus 2.1.x is a great source for documentation.

This is the Exim transport I'm using (works with 4.10 and 4.12) to
deliver via LMTP over TCP:
local_delivery:
driver = smtp
protocol = lmtp
hosts_override
hosts = localhost
allow_localhost
return_path_add
For the above to work, you will need to tell lmtpd to pre-authenticate
any LMTP connections, otherwise you'll also need to configure Exim to be
an SMTP AUTH client. The first (pre-authenticated lmtp connections) is
quite a bit simpler.
These two commands should get you started:
"man lmtpd"
"vi /path/to/cyrus.conf" <- feel free to substitute for your editor of
choice
This is what I've used to deliver via Cyrus's "deliver" program (works
with 4.10, should work fine with 4.12):
local_delivery:
driver = pipe
command = "/usr/sbin/cyrdeliver ${local_part}"
return_path_add
return_output
message_prefix =
user = cyrus
Note the Debian specific /usr/sbin/cyrdeliver and the Debian specific
user cyrus. You may need to specify a different user and command line
for that transport to work under FreeBSD.
The deliver program is also used for Cyrus "plus" addressing - where a
message to "phil+exim.users@???" will be delivered to the Cyrus
mailbox "user.phil.exim.users" rather than my INBOX.

IME there isn't one. The CMU folks recommend using LMTP over TCP or
unix sockets - no matter what MTA you use - on general principle, mostly
for perfomance reasons.
