For the record: I was able to track this down with Oli (thx again!!).

1) In SRD3 the MPLS Half Duplex VRF (HDVRF) Feature is (still?) hidden
an you must use "service internal" to activate it.

2) The RADIUS Profile for PPP HDVRF Sessions should look like this...

  Cisco-avpair="ip:vrf-id=VRFTEST downstream VRFTEST-DOWN",

...and *not* like this as I tried it before:

  Cisco-AVPair="lcp:interface-config#2=ip vrf forwarding VRFTEST
	downstream VRFTEST-DOWN"
  Cisco-AVPair="lcp:interface-config#3=ip unnumbered Loopback102"
