I've had the same problem (at least wrt to X), but it seems to disappear
when cold-booting. It even works when I boot with modeset=0, kill X, then
reload the i915 module with modeset=1. Maybe the kms is a bit flakey when
X played with it for too long beforehands.

But kernel modesetting for the framebuffer console always works, so
YMMV.
