As is, this patch is completely broken.  Any attempt to create a
mipmapped 4Kx4K texture on 965 will break.  At the very least,
MAX_TEXTURE_LEVELS and MAX_TEXTURE_RECT_SIZE in src/mesa/main/config.h
also need to be increased.  MAX_TEXTURE_LEVELS is used to size arrays in
various structures.

Keith, why didn't you use the patch that I sent you?  It correctly
increased these constants while only exposing 2Kx2K textures in the
software rasterizer.
