Assuming that:

  2 = PXP feature is supported but should be ready soon (pending
      initialization of non-i915 system dependencies).

really means, "it'll be ready soon or there is a bug somewhere",

If Mesa finds that it can't really rely on that, we may have to decide
on a different approach in how to use that return value.

Is it possible to hold on for another ~12 hours to see if Lionel wants
