Is the lack of these keys causing you a problem? IIRC they are used by
the builder to communicate with hvmloader (the pre-BIOS loader used in
HVM guests) so it can setup ACPI tables etc as appropriate. Nothing else
should be using them. They are documented as INTERNAL in
docs/misc/xenstore-paths.markdown.
