Works because in this configuration you are using KMS. But i suppose that if you disable KMS by passing i915.modeset=1 to that kernel, your system will hang.
Can you confirm?Pay attention to /etc/modprobe.d/i915-kms.conf: i don't know if it overrides the kernel parameter. Just to be sure i renamed it.
