I suppose that VT_ACTIVATE means "make the specified virtual console the active one". With a multi-attach console system this doesn't make any sense anymore. However, the expectation is that the system display client (the default vga client that is started at boot time and runs on the system console) is frobbed in the specified way. So the console *client* needs also to be a server and register in the filesystem. Then it needs to listen to such requests. This is particularly important for the vc switch with the X server. In that case a special synchronisation must happen because both programs access the same resources. This si the general answer. For the specific question you asked nothing can be said, because none of the options make sense without knowing the context in which they would be applied.
