9.1 and PS/2 Wheel Mouse

Hi Been running SuSE 4ever! My machines are connected to a KVM switch. When shifting between machines I always have to switch between ttys to have my mouse working again. Otherwise it goes crazy :D --> ctrl + alt + fX This works in 9.0. In SuSE 9.1 this does no longer work. The only way to reinitialize the mouse is to unplug it and plug it back in again. Is there another mouse driver I should run to solve this? Thanks for any suggestions, this is annoying :D Regards /Mattias
