80860104 Intel Corporation 2nd Generation Core Processor Family DRAM Controller seems to work with Linux 3.5.2, but so far 3.6.0-rc1 doesn't show any driver loaded. Used the same config on bother kernels. Driver should be agpgart-intel. It may be the reason that fullscreen OpenGL apps give a black screen. (2012-08-17T12:35:50+00:00)
