KVM with DVI monitor recommendations

Is anyone using two computers with one DVI monitor, keyboard and mouse? I am shopping for a KVM now and want to make sure I get one that works with openSUSE and does not have any problems, delays when switching etc…

I have been looking at http://is.gd/Wjq147 GCS932UB 2-Port USB DVI Cable KVM Switch with Audio from IOGEAR.
The footnotes about Win7 at the bottom of the description makes me wonder a little.
