100% reproducible.

Verified to happen without compiz.
Also disabled pageflipping in DDX, although it won't be active without
compiz
anyway.

OK, so it looks like PDISPLAY doesn't like us meddling with disabled crtc.
Thus the attached patch fixes the problem (it makes cursor restore to happen
after modesetting).
