Wireless Joint

I'm curious if I can use GoldenOrb firmware directly on the NEXS2GO (not the Haven Technologies variant) and if so, what the Router Model would be for it to work properly. I don't want to brick the thing and still want my EM9191 and eth ports to work as expected. Would the "Generic x86" version work? Is it all trial an error? It's listed that the NEXS2GO supports any openwrt firmware on the Haven Technologies website, I'm just not sure what this specific board works with firmware wise.
