I am running a lowly ;-) 12.2 Release ....
Cisco Internetwork Operating System Software
IOS (tm) C2600 Software (C2600-JK9O3S-M), Version 12.2(23a), RELEASE
SOFTWARE (fc2)
I found this some time back (by cheer beginners luck I guess) when I was
switching using the new-style CONNECT statements.
Please note that if you add CONNECT statements for this interface to another
interface, it will however act as an ordinary frame-relay switch.
It also works on a 2522 which is my frame relay switch.
And no need to disable keepalives.
Kind regards,
Koen.

But you aren't switching then. :)
Very interesting though. My frame switch won't let me do that! Tells me
I've gone insane and need to rethink life.
What IOS are you running on R3 there?

Scott, I think there is a way around, create a subinterface on the router
acting as DCE:
This way you can do both switching and being a L3 endpoint at the same time.

If you use no keepalive, this is what actually avoids using LMI. Don't
forget to use the same DLCI on each end. DCE/DTE doesn't matter without LMI
(other than clockrate things).
If you use frame-relay switching, then you also have to consider that the
interface with the "frame relay route" is NOT participating as an actual
reeachable L3 interface. It's in an L2 switching mode per your commands.
So consider that and the effects it will have on your topology. (e.g.
making things not usable!)

So this is a back to back connection ? If yes then I see two way you can do
this.
First, no keepalive at both ends
Second, Configure one end with frame-relay switching (global conf) and
frame-relay intf-type dce (interface conf)

I have another question and need some helps.. R5 and R3 are connected with a
serial connection(the connection is good, ppp works fine). I want to have
frame-relay running between them but with no luck so far. The interfaces
were up on both ends, but both routers never learned /32 host route from
other ends, so I can not ping other end at all.
Did I miss anything or did something wrong?? thanks.
