Title:
  legacy nvidia drivers fail to work with latest kernel

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  i have a MacBookPro3,1 with a NVIDIA Corporation G84M [GeForce 8600M
  GT] (rev a1) video card. while in ubuntu 15.10 everything worked fine,
  after the upgrade in 16.04 the legacy nvidia-304 drivers do not. the
  X11 fails to start, the relevant lines in the /var/log/Xorg.0.log file
  are

  [  3021.745] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0.  Please
  [  3021.745] (EE) NVIDIA(0):     check your system's kernel log for additional error
  [  3021.745] (EE) NVIDIA(0):     messages and refer to Chapter 8: Common Problems in the
  [  3021.745] (EE) NVIDIA(0):     README for additional information.
  [  3021.745] (EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device!
  [  3021.745] (EE) NVIDIA(0): Failing initialization of X screen 0
  [  3021.745] (II) UnloadModule: "nvidia"

  and the journalctl --dmesg gives

  kernel: NVRM: failed to copy vbios to system memory.
  kernel: NVRM: RmInitAdapter failed! (0x30:0xffffffff:867)
  kernel: NVRM: rm_init_adapter(0) failed

  nevertheless, the nvidia kernel module is loaded without a problem.

  i also tried more recent versions of nvidia-X but without success.
  they either fail with the same messages as above or they do not
  support the video card.
