That's the first line *before*, not after.  ssgInit enables the state, so
the glColorMaterial call is required before that in order for subsequent
disables to work (with NVidia cards/drivers).

I've spent a lot of time trying, even tried fixing the SSG code, read ever
word of the documentation, then wrote the mailing list found that nobody
here has known either.

When you get some time to run that test program, and if the triangle is
white, you can see them problem clearly on your own machine: SSG apparently
doesn't let you give objects a non-white material without using per-vertex
color.  I've used a lot of 3D APIs over the years, and this is first time
i've ever seen a limitation like this.
