It might help if you give a more complete description of what you're
trying to achieve. The list of things you're trying to do or want don't
make a lot of sense on their own.
For example, are you modifying Xen? Or just guest code? If you're
modifying Xen, it's pretty easy to remove the special case for trap 0x80.
