Subject: Port the SiS DRM to FreeBSD. This includes the ability for the DRM to
     allocate framebuffer memory without sisfb, and a new ioctl to be used    
 by the X Server which tells the DRM what region of framebuffer memory     to
 allocate from. Also fixes a possibility to panic the kernel I     believe.
 Tested on linux with sisfb and FreeBSD (without sisfb) with     new DRI only.
