Hmmm, and indeed all is not as well as it would at first have seemed.

It works fine, as it did in my testing the other day, with
dom0_mem=3D256M, and produces the output above.

However, if I use larger dom0_mem, I do get output with high at
0x40000000 as you predicted --- and immediately after that, a panic
"HYPERVISOR_mmu_update failed".

I couldn't easily capture a backtrace this morning, but it's easily
reproducible so I can do so a little later when its more convenient.
