I think the "GL 1.1 (GL_EXT_texture)" comments could be dropped.

Indent comment.

Maybe use two nested loops here:  one for the three test types and one 
for the texture target typs.

Looks good otherwise.

BTW, here's the output (again?) from NVIDIA's driver:

bin/initial-texture-state -auto
Expected initial value of GL_TEXTURE_DEPTH to be 0, but got 1
Expected initial value of GL_TEXTURE_DEPTH to be 0, but got 1
Expected initial value of GL_TEXTURE_DEPTH to be 0, but got 1
PIGLIT: {'result': 'fail' }

Looks like a bug in their driver.
