Warning: I'm guessing here!

Actually I got this from the list so thanks goes out to other
member of the list. See where I put the note above (***), that's
where I add my patches. First I'd take a look at the kernel-2.6.spec
and find the last patch. Just before:

# END OF PATCH DEFINITIONS

I'd add something like:

Patch19999: my-patchfile.patch

Then a little later in the file:

#%patch10004 -p1

%patch199999 -p1
# END OF PATCH APPLICATIONS

Then I'd put my patch file in /usr/src/redhat/SOURCES/ and
continue the process. Just make sure that your patch isn't
already in there.

I hope that helps.
