this is a limitation of the texture. Bump mapping requires filtering in texture space, but since AO is procedural map dependent on scene, there is no texture space. It is the same reason why for example fresnel won't work. But I guess I could fake it so it blends results of 2 bump maps... not 100% correct, but probably close enough

Ah, I remember now. I stumbled across this fix before but I forgot.

It does seem as if this could be fixed though without the need for this.

Thanks for the help Maru.

For others (see attached). Mesh must have dense tessellation.
