On my 2010 (MBP 6,2) model the intel_chipset_data worked out of the box.
I see now that your model is the 13'' Nvidia only MBP - I somehow
assumed that a higher model number is the 17'' which is very similar to
mine - sorry!

There exists a package called
> nvidia_bl-dkms
Did you try that too?

In case nothing works, the original author (Mario Schwalbe) extracted
the backlight control interface from a Bootcamp driver:

Bug description:

MacBook Pro 7,1 has a nvidia chipset (MCP89 / graphics: Geforce 320 M)

I tried to add the following lines into mbp_nvidia_bl.c:

        {
                .callback       = mbp_dmi_match,
                .ident          = "MacBookPro 7,1",
                .matches        = {
                        DMI_MATCH(DMI_SYS_VENDOR, "Apple Inc."),
                        DMI_MATCH(DMI_PRODUCT_NAME, "MacBookPro7,1"),
                },
                .driver_data    = (void *)&nvidia_chipset_data,
        },


At bootup, 
$ cat /sys/class/backlight/mbp_backlight/brightness
15

but,
$ echo 3 >  /sys/class/backlight/mbp_backlight/brightness 
does nothing on the brightness, except that
$ cat /sys/class/backlight/mbp_backlight/brightness
3

If you need some command line outputs, I can provide them.

Thanks
