Yessir, any non-nvidia chipset that doesn't support SLi you will need a hacked driver. As of now, there are NO hacked drivers for G80, but hopefully that will change in the near future. With the DFI Ultra-D, you can connect to bridges on the chipset to enable it to a SLI-DR. New revisions have a layer of epoxy to prevent this, but you can always scratch off the epoxy.
