This is an application bug. It is using OpenGL 2.0 features on a driver restricted by the capabilities of its hardware to OpenGL 1.4, so understandably tries to dereference a NULL function pointer when calling glGenBuffers. However if the application truly wishes to be cross-device, it can check for ARB_vertex_buffer_object and use the glGenBuffersARB [and friends] extension points instead.
