Take it from a Thinkpad X60 owner, the Intel GPUs from that era are absolute trash. They don't support OpenGL 3.0 on any platform (in fact, they didn't gain 3.0+ support until Sandy Bridge in 2011(!)) so don't expect any of this recent GPU-centric work (which seems to be targeting OpenGL 3.0+) to work on these GPUs. It would probably work just fine on the contemporary Radeon and GeForce cards since they support OpenGL 3.3.
