If you're going to attempt this test on compatibility profile, you need
at least 2.0 (because ARB_texture_buffer_object requires it), and you
need to check for at least the GL_ARB_texture_buffer_object extension.
If you take my other comment (below), you'll also need either OpenGL 3.0
or GL_EXT_texture_integer.
I think the right thing is to request 3.0 for both core and compat, then
check for GL_ARB_texture_buffer_object.

It seems like there are graphics cards in the world where a 2Gb TexBo is
possible. At some point we'll scoff at any value you can pick for a
test like this, but we can at least swing for the fence and try a
texture with a larger pixel format. Maybe GL_RGBA32UI? That would
attempt 32Gb... that should have a bit more longevity.
