XWayland on the RaspberryPI

Greetings all,

I am trying to make XWayland run on a Raspberry PI, so I am building
wayland/weston and the xserver xwayland branch from here:

  git://anongit.freedesktop.org/xorg/xserver

As well as the wlshm (now moved as wayland) driver: git://
anongit.freedesktop.org/xorg/driver/xf86-video-wayland

When attempting to start a x11 app, the xserver effectively is started, the
wayland x driver loads successfully but when attempting to "subload" the
framebuffer driver, it segfaults. This fb driver has been built as part of
this same xserver.

[  1056.806] (II) Loading sub module "fb"
[  1056.806] (II) LoadModule: "fb"
[  1056.808] (II) Loading /root/weston-bin/lib/xorg/modules/libfb.so
[  1056.811] (II) Module fb: vendor="X.Org Foundation"
[  1056.811]    compiled for 1.15.0, module version = 1.0.0

[  1056.812] (==) Depth 24 pixmap format is 32 bpp

[  1056.813] (==) wayland(0): Silken mouse enabled
[  1056.815] (EE)
[  1056.815] (EE) Backtrace:
[  1056.815] (EE)
[  1056.816] (EE) Segmentation fault at address 0xe7933016
[  1056.816] (EE)
Fatal server error:
[  1056.816] (EE) Caught signal 11 (Segmentation fault). Server aborting

The contents of the xorg.conf file looks like so:

Section "Device"
        Identifier "Device"
        Driver "wayland"
EndSection

Any hints on what I might be missing would be greatly appreciated, or even
hints on how to debug this fault, as there is no timeframe to gdb attach
against the xserver before it dies.

Thanks in advance
Albert
