ok, here is a list of valid values with the old nvidia drivers (96.73)

GeForce, GeForce2, Quadro, and Quadro2 Pro
    0                  FSAA disabled
    1                  FSAA disabled
    2                  FSAA disabled
    3                  1.5 x 1.5 Supersampling
    4                  2 x 2 Supersampling
    5                  FSAA disabled
    6                  FSAA disabled
    7                  FSAA disabled

GeForce4 MX, GeForce4 4xx Go, Quadro4 380,550,580

    0                  FSAA disabled
    1                  2x Bilinear Multisampling
    2                  2x Quincunx Multisampling
    3                  FSAA disabled
    4                  4x Bilinear Multisampling
    5                  4x Gaussian Multisampling
    6                  2x Bilinear Multisampling by 4x Supersampling
    7                  FSAA disabled

GeForce FX, GeForce 6xxx, GeForce 7xxx, Quadro FX
    0                  FSAA disabled
    1                  2x Bilinear Multisampling
    2                  2x Quincunx Multisampling
    3                  FSAA disabled
    4                  4x Bilinear Multisampling
    5                  4x Gaussian Multisampling
    6                  2x Bilinear Multisampling by 4x Supersampling
    7                  4x Bilinear Multisampling by 4x Supersampling
    8                  4x Bilinear Multisampling by 2x Supersampling
                       (available on GeForce FX and later GPUs; not
                       available on Quadro GPUs)


so which value is invalid (apart from "-1")?

and as cyrille has pointed out, this has changed with newer driver versions.

people who don't want to think about it, should use a settings-tool that
comes with their hardware (e.g. nvidia-settings)
