Hmm, it works for me:

  $ gpg -K --fixed-list-mode --with-colons heine
  sec::1024:1:586B85BE114A05E1:1116949944::::::scESCA:::D2760001240101010001000003470000:

  ssb::1024:1:7CF434FA0521AD19:1116949976::::::a:::D2760001240101010001000003470000:
  ssb::1024:1:2D1D6B157FE2DF37:1116950005::::::e:::D2760001240101010001000003470000:
  
Note that this is the full AID and not just the serialno part.  From
doc/DETAILS:

  15. Field   Used in sec/sbb to print the serial number of a token
              (internal protect mode 1002) or a '#' if that key is a
              simple stub (internal protect mode 1001)

--fixed-list-mode ist important and should in fact be used by all
applications.  It is available since version 1.0.5 and does not
anymore merge the first UID with the PUB line.


Salam-Shalom,
