HVM is hell ^^
Xen exists to avoid emulation.

For i386  (small instances) EC2 either needs to update to a
non-antique version of Xen or support for not using linear pagetables
needs to be restored to xen/pmap.c.

For amd64 (medium and large instances) a new xen/pmap.c would need to
be written. This isn't a great deal of work, but most users seem to be
having a great deal of success with just running HVM with PV drivers.
