With the given patch from airlied:

-    xf86InitialConfiguration(pScrn, TRUE);
+    if (drmmode->mode_res->count_connectors != 0)

     drmmode->event_context.version = DRM_EVENT_CONTEXT_VERSION;
     drmmode->event_context.vblank_handler = drmmode_vblank_handler;

The crash goes away however radeon still isn't listed as a provider
