1 Make a back up of lilo.conf or grub.conf depend on your system.

2 To remove the kernel option from lilo or grub , you can modify /etc/lilo.conf (or /etc/grub.conf) then run lilo command as root.

3 To remove actual kernel , delete System.map-kernelversion , vmlinuz-kernelversion , bzImage-kernelversion . Before you reboot make sure there is no broken link in /boot dir and image option is pointing correctly .

4 If you accidently srew things up, use a bootable cd and change it back. good luck

Good luck

Just an additional note: If your new kernel works properly and you deleted the old one like poopoo explained, you might have some unrequired kernel modules in /lib/modules/<old-version>. To safe some space, you could delete them as well.

Yeah, the method posted by poopoo is not good if you are removing a kernel installed via rpm. You are better of doing,
Code:
$rpm -qa | grep -i kernel
A list of installed kernels will be listed. Remove the one you don't want by doing
Code:
#rpm -e kernel-version
Running the command above also removes the kernel from the list of available kernels in grub so you don't have to edit grub manually.
