Is that right way for control panel to have such assumption about page
size of Xen? Especially for architectures supporting multiple page size
like IA64, we need a control panel able to run on Xen with any page size
configured, without modification. Even on x86, we can't eliminate the
possibility of special version of Xen + xenolinux with a default 2M page
in the future. :)

A cleaner way may be to add page size info in DOM0_GETDOMAININFO,
together with tot_pages.

Thanks,
Kevin
