ScrnInfo->pixmapPrivate only existed in order to catch invalid access to the framebuffer by making the backing data NULL across the VT switch. This was causing more confusion in the higher layers during mode setting without any real benefit, so remove it. v2: Kill ShadowModifyPixmapHeader() as well.
