Thanks for the link, Sebastian.  Used it, and even had video for a 
little while.  Today, I found this link:
http://openfacts.berlios.de/index-en.phtml?title=Linux+UVC

It calls for moving the uvcvideo.ko file:
"The webcam audio interface must be initialised before the video 
interface. Linux will by default initialise the video interface first, 
so you need to remove the uvcvideo.ko module from the /lib/modules 
subdirectory where it gets loaded automatically, and load it manually 
after plugging the webcam."

I'm now trying to find out how and where and what steps I take to do this.
1]  Move uvcvideo.ko to /home/tom/temp/uvcvideo.ko
2]  Plug webcam in, and reboot
3]  Load module manually  ????  Don't know what command to run to do 
this.  Do you?

It also says I can add the line, but don't know where, as there's no 
modprobe.conf.local file in my FC8 system.

Just add the following line to your //etc/modprobe.conf.local/ :

 install uvcvideo /sbin/modprobe snd_usb_audio; /sbin/modprobe --ignore-install uvcvideo
