HI, Mark
Will you please try to boot the system with KMS enabled and see
whether the X still fails to be started?( Had better compile the I915
driver as built-in kernel and add the boot option of "drm.debug=0x06").
If the X can't be started, it will be great that you can attach the
output of dmesg, lspci -vxxx.
thanks.
Yakui.
