I see three different perspectices:

#1
Frame Relay and ATM can be used as feeder access links to an MPLS core 
network. IE: IPoFR and IPoATM. See ATM alot in DSL networks.....Frame Relay 
aloi in Leased Line replacement services.

#2
Frame Relay and ATM may be carried with an MPLS Core, encapped in MPLS 
headers. I cannot recall all the methods, but one is PWE3. Kompella and 
Martini may do some or all of PWE3 also.

#3
And ATM Core, (NOTE: Not Frame Relay) maybe upgraded or built from scratch 
that also supports MPLS. This is commonly known as Ships in the Night. IE: 
An ATM Switch that will Cell Switch ATM only Cells and at the same Time is 
able to perform MPLS Labeling on IP/MPLS traffic.

Clear as mud?
