If all you need is headers sufficient to build a module,

yum install kernel-devel 
or
yum install kernel-smp-devel

should do it. If you need the full source, I'm not sure how to use yum, but 
you can get the rpm matching your kernel from:

ftp://ftp.scientificlinux.org/linux/scientific/40rolling/SRPMS/vendor/original/
or updates:
ftp://ftp.scientificlinux.org/linux/scientific/40rolling/SRPMS/vendor/errata/

or your local mirror, and then use rpm to install it, ie:

mkdir -p /usr/src/redhat/SOURCES	(dir may not exist causing error)
rpm -ivh <kernel rpm filename>

I briefly played with a yum command that "should" work:

yum localinstall <kernel rpm filename>

but it failed with the error:

[root@grolsch errata]# yum localinstall kernel-2.6.9-22.0.2.EL.src.rpm 
Loading "kernel-module" plugin
Setting up Local Package Process
Examining kernel-2.6.9-22.0.2.EL.src.rpm: kernel - 2.6.9-22.0.2.EL.ppc64iseries
kernel-2.6.9-22.0.2.EL.src.rpm: does not update installed package.
kernel-2.6.9-22.0.2.EL.src.rpm: does not update installed package.
Nothing to do
[root@grolsch errata]# 

If anyone wants to investigate that yum error, I'd be happy to help test.

Hope this helps.
