yum installing an outdated kernel

[Steve Brueckner]

I'm trying to use yum to install old kernel versions but can't seem to pull
it off.
Yum search kernel tells me that the kernel exists in updates-released, which
I have enabled.

I've tried:
# yum install kernel-2.6.11-1.1447_FC4
which returns "nothing to do", and I've tried:
# yum --obsoletes upgrade kernel-2.6.11-1.1447_FC4
which returns "could not find update match for kernel-2.6.12-1.1447_FC4"

So my question:  is there a way to install an older kernel with yum?
If not, what is the next easiest method to install an older kernel?

Thanks,
