Kerry, is i915 is not supporting, is just because it is not claiming the device. or the hardware interface to graphic device (0x8086, 0x8108) is supported by i915 or it is not compatible to i915 supported hardware.
Since the generic vgatext, is claiming and device works fine. As a simple test, if I add a driver alias for i915 "pci8086,8108" will it work?
