Ok, I must have interpreted the question wrong. Here was the question from
the practice lab:
"The initial configurations for this lab provide Frame Relay connectivity
between R5-R2 and R5-R4. There should not be any Layer2-Layer3 mapping
between R2 and R4."
"You are required to use the point-to-point OSPF network type on R2 and R4
S1/0. R5 must be configured for point-to-multipoint."
You can either interpret that as "Don't add layer2-layer3 mapping" or "We
didn't do it initially, but you can."
I chose the former and tried to get it to work without the mapping. Finally
I gave up and added it in there just so I could move on with the rest of the
lab. Ironically, the grading script didn't count off for it.
Thanks for the help of everyone that replied. I appreciate you guys looking
at it for me. At least I learned something valuable in this little goose
chase. :)

Steve,
As far as I can see, everything works the way is should be over there.
Yes, you can see a /24 on every spoke because they both have a
connected interface to the subnet. But you should not expect the
spokes to be able to ping each other because you havent put a FR
mapping for them.
If you want to see the OSPF point-to-multipoint network type in
action, you should try and advertise a lookback interface into OSPF on
the spoke and see how you can reach it from the other spoke.
Alternatively, if you really want to be able to ping between spokes
via the hub, then you should make the spokes' OSPF network type to be
point-to-multipoint and the interfaces will be advertised as a /32 as
you are expecting.
