scroll wheel stops working after KVM-switch

[nicals wahlgren <niclas.wahlgren@gmail.com>]

Using unstable, scroll wheel works fine. But each time I am shifting 
between computers and back to debian scrolling is not working. Doing
>modprobe -r psmouse
>modprobe psmouse
gets scrolling back.

Any ideas on how to keep scrolling working without having to do modprobe?
