I've done it too, without FDE for now. My x200 feels good with coreboot and OpenBSD, there are no random lockups that Scott mentioned.

We both get this error: >error: [drm:pid0:intel_pipe_config_compare] *ERROR* mismatch in >adjusted_mode.flags(DRM_MODE_FLAG_PHSYNC) (expected 0, found 1) >pipe state doesn't match! Also I don't have this error, but I have another! Would be nice if someone told me how to fix it, though I cannot even find what's broken, if anything. dmesg follows.
