Removing old kernels with yum?

[WipeOut <wipe_out@xxxxxxxxxxxxxxxxxxxxx>]

Hi,

How do I remove old kernels with yum??

If I do a..
# yum list "kernel*"

I get..
Installed Packages

So if I try..
# yum remove kernel.i686
it wants to remove all of them..

I have tried specifying the version a couple of ways but then it doesn't 
find anything to remove..

So how do I do it?

Thanks
