Now tested and it works. Patch below.

I'm also going to look into switching Xen to startup on
initial_page_table, since I think the consistency with native would be
useful from a principle of least surprise PoV. However the following is
a useful stopgap if nothing else.

BTW, are there plans to unify 32 and 64 bit WRT the use of
swapper_pg_dir vs initial_page_table?
