Supermicro X9DRG-QF CrossfireX unlock

I have heard that it is possible to get this board working in SLI configuration through a modded BIOS. This is really nice and all but I've got R9 GPUs in there so I am more interested in a CrossfireX mod which seems to be impossible to find. The hardware covers all minimum requirements to get Crossfire going and Supermicro even states that the board should support it but the BIOS is not CrossfireX enabled. I was wondering if it would be possible to mod the latest revision to add this feature.

Here's the product page where any interested modder could grab it: http://www.supermicro.com/products/mothe...DRG-QF.cfm

Thanks!
