For everybody who has the issue with blank screen or panic after the patch: 1. please try the updated patch, https://www.kib.kiev.ua/kib/drm/i915.2.patch 2. if you use "kldload i915kms" to test the patch and get the blank screen, verify do you get panic or just a black screen. It is expected for sc, not so for vt. For vt, if you do get blank screen and not a panic, do not load i915kms manually and run the X server. I am interested if running X server does show proper output.
