I don't think switching physical resolution should be part of the EWMH. So
you will probably have to continue to use VidMode (unless R&R offers a more
Vendor-neutral way to achieve the same effect)

I'd say that "screen" in fullscreen refers to the physical screen (ie
monitor), not to any virtual large
desktop implemented by the WM or the Xinerama extension.

The EWMH doesn't currently say anything about Xinerama (should be in a
future version), but
I think the current practise is to maximize/fullscreen a window not to the
full screen, but only to
the monitor it's currently on.

Look at the very bottom of
http://www.freedesktop.org/standards/wm-spec/1.3/html/x362.html
theres a section containing recommendations for stacking order.
