Yes, see
http://winapi.freetechsecrets.com/win32/WIN32WMDISPLAYCHANGE.htm
(which is IME an invaluable resource for finding information about API
support in old versions of Windows that Microsoft don't want us to
know about).
Of course, Windows 9X didn't support multiple monitors or PnP
monitors, so only resolution changes are relevant to those versions.
But I think w32-display-monitor-attributes-list already handles the
old versions gracefully.
