Alas... tried 12.4(15)T11 (,jk9o3s) but:
* "xconnect" only supports L2TPv3, not MPLS encap
* "mpls l2transport" commands not available
* "show mpls l2transport capability int <if>" only shows "core" 
functionality, edge is not supported:

===
Transport type Eth VLAN
   Core functionality:
     MPLS label disposition supported
     Control word processing supported
     Sequence number processing not supported
     VCCV CC Type CW [1] processing supported
   Edge functionality:
     Not supported

Transport type Ethernet
   Core functionality:
     MPLS label disposition supported
     Control word processing supported
     Sequence number processing not supported
     VCCV CC Type CW [1] processing supported
   Edge functionality:
     Not supported
===

That's about the same output as on my ancient c7200 with NPE-200 and 
100FX interface. I guess the "edge" functionality is what's missing 
every time.

I managed to find a 12.2S image, but it is 12.2(14)S5 and AToM support 
was first included in 12.2(14)S8 according to the docs I found. So I 
guess I'll have to give up here and see if I can get some affordable 
hardware for my AToM labbing. What I've found so far is that a 7200VXR 
with gig interfaces might do it...

(open to suggestions and I'd still be eternally grateful to anyone who 
can throw a c7400 12.2(14)S8 or higher image in my direction).
