Well, if you're installing it with SetTSPtr and SetDefaultTPT (encouraged
if your installer runs at boot time) then you should always expect two RTS's
on the stack (as normal tool functions are required to).

If you're patching the vectors directly then I suggest you either patch them
both or use the method in the previous paragraph to play it safe.
