I tried to set this up myself several months ago (KVM-84) with no luck as primary or secondary. No matter what I did, if I passed through a video card, kvm wouldn't even enter the bios. Presumably because of vga bios issues. I even hacked the nvidia driver on my host system to make certain that the host didn't touch the card at all.
