Have you tried directly connecting the mouse to the system you are loading? If it works without the KVM in the mix then I would suspect the KVM is not passing mouse options correctly for some reason. Have seen similar problems with Belkin KVM switches. In that case when switching between systems the mouse would become erratic jumping all over the screen. Most of the time putting psmouse.proto=imps on the kernel boot line in grub.conf would resolve this problem. You may also want to try replacing imps with bare if imps does not help. There a few other options for this parameter but I have not used them and don't know them off the top of my head. Possibly someone else can point out the other options. BTW: I recommend that no one use Belkin KVM switches. They seem to consistently cause problems for many many people.
