Removing unwanted kernels

[David Niemi]

What is the best way to get rid of many of the old and non-working
kernels out of Grub?  Sure, I could go in as root hacking up Grub and
blowing away files but I know this isn't too good an idea :)  

Here is a list of my kernels:
  [me at Jenny grub]$ rpm -qa | grep kernel
  kernel-smp-2.6.9-1.667
  kernel-smp-2.6.10-1.770_FC3
  kernel-smp-2.6.10-1.741_FC3
  kernel-smp-2.6.10-1.760_FC3
  kernel-smp-2.6.10-1.766_FC3
  kernel-utils-2.4-13.1.49_FC3
  kernel-2.6.10-1.760_FC3
  kernel-2.6.10-1.766_FC3
  kernel-2.6.9-1.667
  kernel-2.6.10-1.741_FC3
  kernel-2.6.10-1.770_FC3

The kernels were installed via up2date and I have read through the
fedoranews page for "yum-remove" at:
http://fedoranews.org/tchung/yum-remove/

Would that be the proper procedure to remove the extra kernels or just
use "rpm -e kernel..." as I found elsewhere.

Thanks
