Question Re: Quadro FX 880M Brightness Issue for Kernel 2.7.1

I have been using my Thikpad w510 for both Fedora 13 [2.6] and now Fedora 16 [2.7.

In Fedora 13 I did not have a problem with the brightness control on the laptop with the Nvidia driver.

Now with Fedora 16 I am not able to regulate the brightness with the Brightness Control.

I have tried adding the line:-
option DWORD|RegistryDwords
Option "RegistryDwords" "EnableBrightnessControl=1"

But in my xorg.conf I do not see a GPU stanza, I see 4 Device stanzas and if I add the word to all or the enties, I cannot start up the Nvidia device - I do not go into graphical mode.

Can I get some clarity on what the entire stanza should look like ?

Other than the brightness I do not have any other issues with the card

Before I go to the native Nvidia driver, I have a question regarding updating a) Nvidia Drivers and b) Updating the Kernel. I have downloaded the driver ready to install:-
a) For an updated driver, I can use:
nvidia-installer --update

Thanks in advance.
b) What happens when the Kenel is updated while the Nvidia is installed, what do I do ?
I use akmod to rebuild my kmod lib, I did see a reference to mkmod, but where is that obtained.
