I have had the same problem with my brandnew Thinkpad T410 with Nvidia Quadro NVS 3100M. To get the Fn brigthness keys working, I had to add an option to the /etc/X11/xorg.conf file into the device section of the nvidia card:
Section "Device" ... Driver "nvidia" Option "RegistryDwords" "EnableBrightnessControl=1" ... EndSection
Maybe this enables the brightness control on the Samsung R70 notebook, too (?)
