yes, i did a clean vista install from original vista-dvd, as i'm not happy with pre-configured systems from any pc-dealer... way to much programs slowing down the system and i never use. so clean vista-install was first choise! and rotate-button just started working after installing nvidia-display-drivers! so i guess with clean xp installation its the same. after installing the right display-drivers (whatever may be the right ones...) AND installing the quicklaunch buttons will do the trick (hopefully).
