In your case then, it might be better to just wait for your distro
maintainers to provide a compiled kernel rpm build for you.

If you're desperate and still want this to work, you could hope to find
the official cx25840 svn/cvs repository.  Download the version matching
your installed kernel and only compile that module.  (IMO, unless you're
coding, this is more like hacking to make things work.)

Best method, download the SRPM and compile the whole kernel.  I think
the SRPM's usually come with a default config file.  (Configuring a
kernel is the most time consuming, other then building it is as easy as
typing make bzImage and letting it do all the work.)  Come to think, I
don't think you can apply a patch without first specifying the patch
within the .spec file, and then re-rolling the SRPM. :-/

FYI  I use Gentoo.  Manually rebuild my kernel with each release with
using the previously used .config file.  Pretty easy.  Easier then
finding the dumb "Start Menu" button in windows and then trying to click
on it! <grin>
