The correct SSDT was the SSDTTime-generated one, which didn't end up defining TRP0, but instead just passed a series of bridges from PCI0 to GFX0. All I needed to do next was to add some basic properties under DeviceProperties and change the SMBIOS to MacPro7,1.Ah! It was an eGPU! That explains the unusual number of bridges and the error message: The external enclosure is not yet initialised when ACPI tables are loaded.
You've found the solution to a problem which had escaped us so far.
Which SSDT is working? My half-desperate SSDT-BRG? The one from SSDTTime? Both?
What would be really neat now is to understand what are the changes between MBP16,x and MP7,1 to be able to retroactively apply them to the laptop SMBIOS profile.
