Well, dom0 is directly mapped. In other word, dom0 physical address == 
host physical address. So if we allocate memory below 1GB in Xen, then 
it will mapped below 1GB on dom0 as well.
The patch I suggested would try to allocate as much as possible memory 
below 1GB. I believe this should do the trick for you here.
