You seem to have done quite a bit (possibly more than most) already, but I was thinking of something more you might like to attempt: You have set up your video card install for catalyst, but what if the install cd could identify between the major types (nvidia as well), and then install the relevant driver(s). I reckon this would be doable at least for the catalyst and detonator drivers, and maybe even for others. It makes the cd install much more compatible with varying computers in a network environment. Worth a try, I reckon
