Just bump the revision number by 1, so it will update from yours.  You 
will have to watch for regular updates and repeat after any of you 
modified packages get updated.

For instance:

1. install the source rpm from updates for gdm (rpm -ihv gdm...src.rpm)
2. cd ~/rpmbuild/SPEC
3. vi gdm.spec
4. bump the revision (not version)
5. cd ../BUILD
6. untar the gdm*.tar.gz
7. cd gdm<version><revision>
8. modify as desired
cd back to the BUILD directory
9. tar up the sources into a file name that matches your new 
version.revision from the spec file you edited
cd ../SPEC
10 rpmbuild -ba gdm.spec (specify arch if ya need to)
11. rpm -Uhv <new_rpm>

All set!

Hope there is a clue there somewhere for ya.
