It is clearly not possible. "V" in VAO/VBO stands for Vertex. OpenGL < 3.1 can
use buffers for per vertex data and not for uniforms (which stand for the
values used by shaders which are common for all vertexes). The meaning of
ARB_UNIFORM_BUFFER_OBJECT extension is to allow buffers to be used for
uniforms. No such extension, no buffers for uniforms: just plain uniforms with
accompanying limits. Those limits are not as bad as 256 though, even for your
rather old card it is 4096 as we found out.
