<pre>I've just tried the "LinearFramebuffer" driver option along with "ZaphodHeads"
and found that I run into an assertion when doing my xfce-terminal test:
sna_accel.c:2430: sna_drawable_move_region_to_cpu: Assertion
`has_coherent_map(sna, priv->gpu_bo, flags)' failed.
Note that the line number might be a little out of sync since I've added some
extra debug lines.
That made me come to the idea that the issue might be related to the fact that
in zaphod mode there are more than one framebuffers and that some piece of code
might be not prepared for that good enough. What do you think on that idea?</pre>
