On openSuSE, Xorg start fails, if modeset is enabled (https://bugzilla.novell.com/show_bug.cgi?id=856760).
This is caused by the fact, that the fbhwdev part in Xorg uses smem_start/len of the "fix" part, which is
not initialized by the the cirrus drm driver.
The attached patch fixes this problem. I can't spot such a initialisation in HEAD,
so I forward this patch.

Martin
