That's to make Dom0's memory map holes match those of the physical
machine. I think the plan is to relocate those pages to the top of
Dom0's physical address space instead of freeing them, but so far
this wasn't implemented. As this is only being done in the pv-ops
kernel, switching to 2.6.18 or a forward port thereof (as also
suggested by Keir) should get you to see the full memory amount in
Dom0.
