I am getting the same error on plain x86 hardware (bare or in KVM).

In the file xserver_xorg-server-1.7.5/dix/colormap.c (relative to the
buildroot build area) the following code:

ca.  line 395, function CreateColormap

    /*
     * Security creation/labeling check
     */
    i = XaceHook(XACE_RESOURCE_ACCESS, clients[client], mid, RT_COLORMAP,
                 pmap, RT_NONE, NULL, DixCreateAccess);
    if (i != Success) {
      FreeResource(mid, RT_NONE);
      return i;
    }

the value returned from XaceHook is not Success, so CreateColormap
fails here. It returns to the function miCreateDefColormap located in
xserver_xorg-server-1.7.5/mi/micmap.c, ca. line 314, and then the
caller of miCreateDefColormap (in the fbdev driver) prints the message
you saw.

If I comment out the return after XaceHook, miCreateDefColormap seems
to proceed, but the X server crashes.

I'll try to build gdb for the target and see where this takes me. If
anybody else saw this error and got any more results please share
here.

Hope this helps.

Thanks.

Tried Sourcery CodeBench ARM 2011.09 and everything started without a problem, i.e. no resolve symbols problem, as with BR own toolchain. Sourcery CodeBench ARM 2012.03 had problems compiling xdm - after 20 minutes gcc was still 100% busy compiling/linking xdm.
