fbdev: intelfb: add support for the Intel Integrated Graphics Controller 965G/965GM

Browse Source 
Add support for the 965G and 965GM graphic chipsets to the intelfb driver.  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.
