It might be entertaining to stick another 1GB of RAM in the machine and
see what both native and Xen do.

Also, do you have Windows on the machine? It would be interesting to see
where it puts the MMIO space (it might tell us whether the BIOS is
putting it at 1GB, or whether Linux is re-mapping it).
