Hardware occlusion culling

Our FireGL2/3 boards support the GL_HP_occlustion_test extension, but I cannot find a scrap of documentation on it other that the incomplete version on this web site. Need the right token numbers
for the ones specified as ???'s

Any information that would allow me to access this functionality would be of great benefit.
