[HOW TO] Installing Kernel 2.6.30 (or any latest version available) in Debian Lenny or Ubuntu without having to go through Compiling

I have recently switched to Debian Lenny (from Ubuntu Jaunty Jackalope) and it is quite stable. However, I wanted to try the latest stable linux kernel (2.6.30 as of now) in this machine and see how it goes. However there are not much problems, I just wanted to install it. I went to Debian Kernel Archive and downloaded the packages but it does not seem to work. So I headed over to the Ubuntu Kernel Archive and the kernel there worked. This is how I did it.
