Ok, I cloned the drm tree just to see, and it does seem like it's just 
nouveau that does that whole thing. At least from a quick grep of 
drmGetVersion() calls.

.. but Jesse tells me that it's using feature masks etc, so maybe my 
recollection is about unrelated issues.

So yeah, nouveau seems to "special". Although somebody already said that 
if I'd have had a radeon, I'd have seen similar issues. Maybe the radeon 
driver just doesn't check the version number, and fails in different ways.
