Need some help to finalize AmigaOS4 port of AssaultCube

You should first ask that developer if he is sure that vertex arrays and display lists work flawlessly.

All in all we imho can also commented everything and only loads meshes as some "basic" stuff, without any options, etc ?

Not really, no. The engine relies heavily on said features, not only to render models, but especially to rotate and animate them.

Honestly, I don't know enough about neither OpenGL nor AC's rendering functions to be of much use.
