The interface cfg should be ok.
One side is a PPP link (s1/1), the other is a frame
relay connection (s1/0). The other neighbor is a
router behind R5.
R5#sh ip ospf neighbor
Neighbor ID Pri State Dead Time

And indeed in your set up *is* working.
As the last attempt I have even tried making my ospf
networks type-1 as yours, just in case. No luck.
They become type 1 but still load balancing:
O E1 130.1.78.0/24 [109/84] via 130.1.45.4,
00:00:12, Serial1/1
[109/84] via 130.1.35.3,
00:00:12, Serial1/0
which IOS version are you running?
I'm on
Version 12.4(7.8)
currently.
Anyway is good to know it is supposed to work. If it
happens in the lab I'll close my eye, cross my fingers
and I'll try to configure it.
Not sure I'll have the courage to check if it works,
though. =:-O
