I have a notebook with an Intel Mobile GM965/GL960 Integrated Graphics Controller and with the attached patch the framebuffer comes up. I have tested it a bit with DirectFB to make sure it is working stable. I also have an Intel Mobile GM945 and I compared the results, the programming interface of the 9xx series from Intel is mostly the same, so I think the patch should add all the functionality which the 945GM has.
