Yes, I can now get a Fun Kids radio speech test broadcast (80 kbps mono) which loses its appeal after a short while. I'm also getting D1 Test 1 (speech - 48 kbps mono), D1 Test A (speech - 48 kbps mono), Data&Audio Test (speech & music - 192 kbps stereo) all on the Digital 1 mux.
Who knows, we might get some additional stations as well. Although this is an aside, I wouldn't mind having the audio feed from Sky News broadcast on DAB as a competitor to the BBC's factual news offerings. That would help to fill up another of the empty Digital 1 spaces.
