Take a look in the files/ directory, it contains the applicable patches. 
it will also tell you where to find the files that are being patched. 
Sometimes you just need to regenerate the patches based on the old ones, 
only thing that gets changed is line numbers. But in some cases the 
patches no longer work, or there are new issues than need to be 
addressed within the patch files. Heres a quick lesson on creating patches.

1) cp FileName FileName.orig
2) vi FileName (make changes)
3) diff -U3 Filename.orig FileName >> patch-FileName
4) test the patches to be sure they work.

Hope this helps.
