An update...

(answering myself :) Yep, it does this fine... However, I am having anoth=
er=20
problem with Qt: Xft fonts are rendered too small and with size decreasin=
g=20
proportional to decreasing screen resolution, once the screen is resized.

Keith Packard says:
"Are you smashing DisplayHeight and DisplayHeightMM in the X display=20
structure?  Xlib doesn't do that on it's own as we're not sure it's a goo=
d=20
idea for all applications (yet).  Just do:
=20
        DisplayHeight(dpy,screen) =3D (new display height)
=20
and things may work a bit better."

If any Qt gurus know what's going on....

An addition will be made to the RandR protocol to send an event from the=20
server advising of the change... it will be up to us to make the change /=
=20
prompt the user, etc.

quoting Keith:

"Yes, there are issues as RandR doesn't have a separation between the roo=
t
 window and the screen number.  It may be relatively easy to add the scre=
en=20
number in the relevant places and have things "just work"."

As for the ETA of the extension in the core server, the resize part is a=20
possibility for XFree86 4.3, due sometime this summer. The rotate and dep=
th=20
parts will take longer.
