Hi, the way to "kill" (disable) the nvidia card is through a contributed kernel module: http://linux-hybrid-graphics.blogspot.com/2009/12/solution-to-switch-off-nvidia-card-in.html
I will check again if a BIOS update is available for my Asus UL50VT, but there was no option to change between cards or modes as your Lenovo has :(
The BIOS should have such an option, it is not like choosing at boot time or like switching it live, but will do the trick in the mean time.
