I have the audio working. I'm unable to access the web cam and I do not see anything at the manufacturer's site which suggests what brand it is. I had read elsewhere that Dell was pretty good about supporting its laptops for Linux, yet it appears I'm on my own. So I come here for advice on how to determine what hardware I have.

I followed the teachings at http://en.gentoo-wiki.com/wiki/Webcam and activated in a gunshot mode all the video modules in the hope that genkernel would determine what hardware I had and load the appropriate driver. Alas, no luck.
I tried emerging media-video/linux-uvc, but it failed to build. Others appear to not exist:
