Maybe that's the official line, but it does not appear to actually be
the case.  In particular, I have been unable to find RandR settings
that provide the semantics of -xinerama, of each head being a separate
screen.  Have I just missed something?

xrandr works, in that it operates as it's designed to.  It does not
work, in that it cannot give what I want.  As far as I can tell.

What's that?  It does not appear in xorg.conf(5) as far as I can see.
find | xargs grep in /usr/xsrc makes me think it does not exist in
5.2's X; there are hits, but they are internal function names.

Given the name, I suspect it will, at most, save me from having to hack
on xf86Crtc.c to get a screen that can hold the two monitors I have
been testing with (the built-in 1920x1200 and an external 1920x1080).

Two heads would be enough to help greatly - if they were separate
screens.
