Comment(by bernie):

 Found.  It's EXA's fault... and it seems to be done by design:

 {{{
 #ifdef MITSHM
     /* Re-register with the MI funcs, which don't allow shared pixmaps.
      * Shared pixmaps are almost always a performance loss for us, but
 this
      * still allows for SHM PutImage.
      */
     ShmRegisterFuncs(pScreen, NULL);
 #endif
 }}}

 The reason why it works with fbdev is probably that it disables EXA
 support.
