A lot of people tried already, and everything works. It's not "alternative" or "another" SLI here, it's the same SLI made by NVIDIA. It's just without checks of platform.

Download latest Everest and look at ACPI/DSDT Table section. If you see there SLI Certificate: YES, cert data and HAL report of chipset hardware : Intel X58 on your mobo - then 99.9% that it will work properly. If you don't see both these things - your modification go wrong way, recheck and redo everything again.
