Well, I don't know what "supported" means here.  That page does not specify 
the kernel version what kernel version it uses as a reference.  It also 
indicates that this hardware is supported by the "spca5xx" kernel driver.

I find no kernel module of that name on my FC 6 box.  I took a quick grep 
through the kernel 2.6.18 source, and I find no evidence of the existence of 
this kernel module.  Granted, this wasn't an exhaustive search, but I 
couldn't find anything.

Furthermore, if you actually bothered to click the "Download" link at the 
top of that page, you would've discovered that the driver for this hardware 
is not part of the Linux kernel, but is a separate kernel driver module that 
needs to be downloaded, and built.  That is, normally, a rather delicate 
task, but you got lucky here.  That page contains a broken link to an 
alleged prebuilt kernel module package for FC4.  But, it's fairly easy to 
figure out that the contents of http://atrpms.net/dist/fc6/gspca/ look to be 
rather promising for you.

However, rather than randomly downloading some of these rpms, why don't you 
go to http://atrpms.net, and follow the instructions for adding the atrpms 
repository to yum, then you should be able to get everything going simply by 
running "yum install foo", with your only remaining hurdle is to figure out 
what "foo" should be.

Looks like, at the bare minimum, you should install the "gspcav1" rpm, and 
the correct "gspcav1-kmdl-<kver>" rpm, that exactly matches the kernel 
version you're running.
