This is a long standing problem with Belkin KVM switches. Most people
find that using psmouse.proto=bare or psmouse.proto=imp resolves the
problem. As mentioned this will most likely cause the mouse wheel to
stop working.
I recently picked up an Iomega 4 port KVM switch. Interestingly enough
linux seems to work fine with it but Windows 2000 seems to have problems
with the mouse. :)
