nit: up to Bjorn / Andy, but personally I'd put cheza and non-cheza
changes in two patches.

nit: I'd probably move the delete of the zap shader to a slightly
different place just because the rest of the lines here are deleting
reserved memory regions.

Other than nits this seems OK to me. Not that I know anything about
the zap shader or why a zap shader wouldn't be appropriate for cheza.
