S-Video patch for which kernel?

Hi all.

i tried to make the S-Video output by beagleboard.

and i got the patch file from here:
http://groups.google.com/group/beagleboard/browse_thread/thread/dc11612c4d6533cf/e6d794fbf2d0abea?lnk=gst&q=S-Video#

but could someone tell me which linux kernel i will put it into?
i tried kernels of several version, but i got both patch error and
compile error.

Thanks a lot!
