I don't think Nuke has much in the way of "geo assisted" tracking yet, although there are some tools coming together to help you get geo out of the tracker... you know, dense point cloud poisson mesh type stuff.
pftrack has some nice features in this area. in fact, it's geo assisted stuff is the basis for it's whole object tracking workflow I think your best bet is to try to track it with reliable focal length and film back info, so at least your points have a fighting chance of being in the same ballpark. then you can use the scene tab in the camtracker to try and push and shove your whole scene around to match your geo. not perfect but you can usually get something reasonable going.
