There's no particular benefit of having a 64b dom0  -- it's supposed to be a 
small VM used mostly for control plane functionality, and doesn't need to map 
much memory. 32b dom0 has been shown to be a bit faster and less memory hungry 
than 64b.  I guess XCP might switch to 64b at some point, but there aren't any 
strong reasons for it at the moment.
