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.
