There's only one problem with XInerama: for the most part, 2D and 3D
acceleration will only work on the first head. So, yes, you can do the
video wall but only if you play your video using the XShm driver as
opposed to Xv (atleast, all of this was true of XFree 4.1) OpenGL cannot
be played accross heads.
