She Who Must Be Obeyed seems to have left psyche-list, so I try to stand in... ;-D It's not really a driver issue (although different drivers and different operating systems can be affected differently). I guess all of you who do experience difficulties with the mouse while using KVM switches are using PS/2 mice. The reason is simple: While serial and USB ports are built to be capable of "hot plugging", PS/2 ports are *not*. If you have really bad luck you can even destroy the device and the port when doing so. A good electronic KVM switch handles this by electronically emulating the PS/2 mouse and/or keyboard, while the real device is used by another box. If this doesn't work while switching the box this can lead to a problem. XFree86 is especially vulnerable for this, while other (commercial) X servers have less difficulties, and Windows doesn't seem to notice it at all. I consider KVM switches which show such problems to be defective, thus I request exchange on warranty. I had good expeiences with KVM switches from Cybex, but they (and their cables!) are *expensive*!
