Right. I've found the issue.

I asked debian to install it's Glut package. Which apparently, along
the way installs all the OpenGL development kit (including headers)
{Hurray!}  and Mesa's runtime libraries...

And hence, yes, it appears to be linking against one set and using
another...

So i ended up just clubbing that crap over the head, moved the mesa
libraries sideways and fixed up all the symlinks. One working GL system.

One annoyance is that my glxgears rate has dropped to 40-50 fps. Which
sounds awful low even for an 800MHz machine[1]. "glxinfo" swears all
up and down we're using the Nvidia renderer.

I'm wondering if it's refresh clamped, because there's no tearing in
the image...
