If I had known... :)

Unfortunately, I have not yet succeeded. I modprobed 'sco' and then
ran headsetd as before, but that just prints

headsetd[9417]: Bluetooth headset daemon version 0.5
headsetd[9417]: Configuration phase ended: target bdaddr is 00:1A:45:14:EE:D7, timeout is 90000 ms
headsetd[9417]: Changing state: Idle-->Paging
headsetd[9417]: Changing state: Paging-->Connecting
headsetd[9417]: Changing state: Connecting-->Ready
headsetd[9417]: Changing state: Ready-->Opening

At this point, the headset makes the sound it makes when
a connection is established, but there is no sound coming from it.

After about 40 seconds, the client says:

aplay: main:564: audio open error: Connection timed out

and headsetd writes:

headsetd[9417]: unable to open SCO channel to headset: Connection timed out
headsetd[9417]: Changing state: Opening-->ZombieAppl
headsetd[9417]: Appli closed socket
headsetd[9417]: Changing state: ZombieAppl-->Idle

So something's still broken... :(
