Hi Everyone,

I reversed the if block in setup.c and now my server can see the full 
32GB of RAM. I haven't submitted a patch yet as we have run into another 
(possibly unrelated to xen) issue with this server build that we are 
working on. Once we complete our full testing, a patch will be submitted :)

Thanks
