Re: No GL_ARB_occlusion_query ??
The geforce4mx (of which the geforce4 440go is a version) doesn't support this extension. If the game doesn't find it, it isn't used. I doubt this is the reason the game is so slow. For WoW you need a reasonable videocard and cpu. Sure the first versions of wow had low requirements but they quickly realised for burning crusade that a GeforceFX 5700 or more is really needed. They haven't added really new 3d features or so.
I would say that your videocard is just too weak.
