Re: [Bug 395045] [NEW] mbp-nvidia-bl-dkms does not work with karmic when using kernel 2.6.31-1-generic x86_64

  If I try to load the mbp_nvidia_bl.ko provided with the kernel it
  fails saying that could not identify my device. mbp-nvidia-bl-dkms
  has the changes necessary for my device identification, but does not
  work with the latest generic kernel provided in karmic.
