  You rebuild your kernel without "options INSECURE", and the SVGA driver
can not cope with this chipset unless it can do direct writes i.e. mmap()
the video ram. I think that this is likely a bug.
  I solved it by installing the aperature driver LKM, which I keep hoping
I'll find to make it static. And.. we probably need to PR this.
