No, that won't help. I'm referring to things like Dom0 accesses to the
M2P table it sees, which doesn't cover even nearly all memory. I can't
say whether that can go without problem, but without closely looking
at it I don't think you can assume this would work. Likewise I would
suspect tools issues (if you use the tools from xen-unstable et al),
though I have no precise pointer right now at specific issues.

32-bit dom0 is the standard use model for Citrix product, and I think people tend to run it even with xen-unstable. Its a fairly well-tested combination.
