With this sort of configuration you won't be able to ping your own interface. It may seem counter-intuitive at first but the problem is that the router doing the pinging doesn't have a frame relay map for its own IP address. With the point-to- point interface you had originally this is not an issue.
When you ping your own serial interface the packet usually goes to remote router first, gets bounced back to the local router which then replies to the opposite side, which bounces the reply back to the originating router. This process won't work if the originating router doesn't know where to send the first packet. This is normal behavior for this sort of configuration and nothing to be concerned about.
