I am using X without configuration file. And it crashes after login (X itself starts fine): Program received signal SIGSEGV, Segmentation fault.

I guess this is unrelated to KMS?
(In reply to comment #3) > I guess this is unrelated to KMS? > When I disable kernel modesetting everything works fine.
KMS is setting resizable framebuffer enabled on server 1.5, resulting in DRI1 not initializing. Needs roughly the same treatment as 70e0261208654c6c875ad462da2734c6aa9eeb96 (note that directRenderingType isn't set at I830DrmModeInit time!)
Upgraded to 1.6, things work now.
