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
