nvclock doesn't work on a Samsung R519 notebook

[keyboardsurfer]

Binary package hint: nvclock

I've got a Samsung R519 notebook with a NVIDIA GeForce G105M 512MB VRAM graphics card and nvclock says that it's "Unable to shadow the video bios" even with the -f option which makes it unable to work on Ubuntu 10.04.1 LTS

nvclock version:
  Installiert: 0.8b4-1ubuntu3
  Kandidat: 0.8b4-1ubuntu3

Same problem, in ubuntu 10.10 at least it detects de key of brightness but is not working, i had the same problem in all ubuntu versions, i can't change brightness, only solution to start in windows 7 and chagne it there...
