I think the problem is that your latest patch plops the store page in 
the middle of kernel memory and nothing prevents the kernel from using 
it. In x86, this is handled by allocating the xenstore and console pages 
immediately after the kernel and then setting the pt_base parameter so 
that they are never used. I'm not sure about this, but I don't see 
anything keeping from using it.
I'm off for the night.
