No Oculus Rift is needed to start the demo and no other software except wine is needed to run it (there will be obviously no head tracking).
I can only test it with PRIME, so I don't know if it also happens directly.
I simply start it with With wined3d, it starts and displays fine (but spills out some GL errors). The same command with nine d3d9 enabled, hangs before anything is displayed.
One possibility is that the different programs simply do different things at startup, another one is that they maybe use different unity versions, but in any case, the programs that do not work with nine do work with wined3d.
For example, this one: https://share.oculus.com/app/the-rpg-room (perhaps a signup is needed for this website, to download it, but it's free of cost in any way).

This is with nine:
And after that line it hangs.
And this is with wined3d:
etc.
Some other oculus rift unity applications do work with nine d3d9. Like https://share.oculus.com/app/titans-of-space:
etc.
