Perhaps this solution isn't for you, but might work for some people on 
the list.  I've been using an ATEN KVM for a few years now and was quite 
happy with it.  Good video, even at 1600x1200.  But when I got a new MS 
optical mouse with the two extra buttons, the KVM box was not passing 
those through.  Wanting to use the extra buttons under Windows, I just 
plugged the new mouse directly into the Windows machine, and my old 
wheel-mouse into the Linux box.  Mice, after all, aren't nearly as big 
as keyboards and CRTs!  As long as you only have 2, maybe 3 machines to 
work with, this beats the $150-200 solution of a new KVM, and works just 
fine, for me.
