AFAIK an es7000 with EM64T CPUs works on x86-64. So it is probably not 
needed if you would follow what a real Linux kernel is doing. 

But of course most of the hypervisor codebase is still 2.4-sometime-ancient
so you might run into many more problems there. I suspect they are not
related to genapic though.
