please post your kernel .config.
short summary of the kernel side:
1. all kernel-graphics support is consolidated into i915 module.
fbcon is used by i915 to display the console. kernel mode setting is
needed for userspace x-driver.
2. all other kernel framebuffer-drivers are not to be used together with
the i915 module.
if you honor those two points, you should see the kernel booting up.
if you don't see the kernel booting up, you should probably file a bug.
