Are you running Compiz?  I have a similar problem where Compiz appears to
get confused about the layout of a pair of screens when you rotate one of
them.  The terminal you used to run xrandr should still have the keyboard
focus, so try running "killall compiz" (or possibly "killall compiz.real")
to see if your screens get fixed.  If you start compiz again with the
screen already rotated then it seems to work.

I haven't gotten around to tracking down exactly where the bug is,
unfortunately.
