Even if you do NOT use Nouveau, you can help out the nVidia developers and it will take at most twenty minutes. If you have an nVidia GPU using an NV40 core or newer, they would like you to download some of their BIOS dumping tools with Git, compile and run them, and email the results to them.
The wiki page doesn't doesn't give compile instructions or list the dependencies, but it's very easy and I figured it out without too much trouble. Just git clone the pgtest repository (git://0x04.net/pgtest) and the vbtracetool repository (git://anongit.freedesktop.org/~stuart/vbtracetool), and to compile each one, cd to the directory and just type "make." You need to install libpci-dev and libpciacces-dev for it to work. Once you've got them compiled, the instructions I linked to above are very easy to follow.
This presents NO RISK to your graphics card. It reads from your GPU's BIOS and registers but DOES NOT MODIFY THEM! The worst that could happen is your X server hanging, and that didn't happen for me.
The Nouveau devs already have this info from 68 different computers (including mine,) but could probably use more. Please, if you want to further this open-source nVidia driver, now is your chance to help!
(NOTE: I'm not a Nouveau developer, I'm just posting this on my own initiative.)
