For some reason the server is using legacy multihead mode, which as you've
observed is not all that friendly.  (BTW, in legacy multihead there is *no*
way to move windows between screens.  This is an X server limitation;
xmonad has no control over it.  It's one of the reasons that there exist
hacks such as xmove2.)  I would have expected that there be some way to tie
them together with xrandr, instead of it using legacy mode; but on the
other hand I seem to recall some vendors' video drivers don't support that
part of the xrandr spec.
