More progress with Stretch:
leads to
This means the SGX is up and running and the firmware was loaded successfully.
So the final (?) question is now quite different: why does it enumerate devices but fail with PVRSRV_ERROR_NO_DC_DEVICES_FOUND?
Some thoughts - please help if you know answers:

Some thoughts - please help if you know answers:
- X11 is running and showing a Log In window - could that be a problem?
- What I do not know is if TILER code is included in the newly built kernel or not. Probably yes.
