Note that alternatively, you can make your own kernel-sourcecode rpm by editing 
the spec file once you install the .src.rpm. You will see several "%define"s 
right near the front, one of which is "buildsource" and by setting that to "1" 
(and I usually set the others to "0" so it won't take so long), rather than 
doing the rpmbuild -bp, you can then do something like:

rpmbuild -bb --target i686 kernel-2.6.spec

and you will get your own kernel-sourcecode rpm in the RPMS/<arch> directory.
