[CentOS] gspca tarballs?

Does anyone know of a reliable site to d/l a tarball of gspca? *NOTHING*
I've tried works on those two servers, suggesting to me that there's some
weird bug in the driver that's in the kernel. They remain, as I mentioned,
about the top 15% ok, and the rest green screen (which I've googled to
find other folks, years ago, complaining about), so the only thing left I
can think of is to try to build the driver myself.
