Okay, it is so close now I feel I may succeed!

What I did was:

1. Compile xf86-video-wlshm, with an edit that was in the wayland-build 
script I have:

    git clone git://people.freedesktop.org/~iksaif/xf86-video-wlshm
    sed -i -e s/hosted.h/xwayland.h/ xf86-video-wlshm/src/wlshm.h
    ./autogen.sh --prefix=$WLD
    make
    make install

2. After much futzing, came up with an xorg.conf that does not produce 
an error and uses wlshm (I think, an example of the correct file would 
be very helpful, or a patch to wayland xserver to not need it):

Section "ServerLayout"
     Identifier     "Default Layout"
     Screen      0  "Default Screen" 0 0
EndSection

Section "Device"
     Identifier "Device0"
     Driver "wlshm"
EndSection

Section "Screen"
     Identifier     "Default Screen"
     Device         "Device0"
EndSection

3. There appears to be no way to get weston to tell the xserver to use 
an alternative config file. So instead I rand weston without --xserver 
and replicated it's launch line inside the weston-terminal:

     Xorg -config ./xorg.conf -wayland -rootless :2 &

(adding some rules to weston to locate an alternative xorg.conf might be 
a good idea, or a way to pass arbitrary switches to Xorg).

4. I can run X clients, and they seem to talk to the server:

     export DISPLAY=:2

5. However nothing appears on the screen. If I kill the client debug 
information prints to stdout from Xorg (not from the client, showing 
that there was successful communication):

     (abbreviated because weston-terminal does not do copy & paste to X):
     1 XSELINUXs still allocated at reset
     SCREEN: 0 objects of 112 bytes = 0 total bytes 0 private allocs
     ... other 0 objects
     PIXMAP: 1 objects of 12 bytes = 12 total bytes 0 private allocs
     ....
     TOTAL: 1 objects, 12 bytes, 0 allocs
     1 PIXMAPs still allocated at reset
     ....
     xwl_input_delayed_init

6. Running xev produces some output on the stdout of xev showing some 
events have been passed:

Outer window is 0x200001, inner window is 0x200002

     atom 0x27 (WM_NAME), time 260665416, state PropertyNewValue

Expose event, serial 16, synthetic NO, window 0x200001,
     (0,68), width 178, height 110, count 0
(at this point all output stops, even if I try to click and hit keys in 
weston, and the program waits until I kill it)

Any ideas?
