I'm only familiar with the commandline which I use on my server installs.

First you need to add the jaunty proposal repository to your /etc/apt/sources.list and do an update of your cache.
You can then search your cache for available images using "sudo apt-cache search linux-image-2.6.28-12".

Next "sudo apt-get install linux-image-2.6.28-12-xxxxx" (where xxxxx = server or general or any of the other types) will install a new kernel image and add it to your grub-menu where you can select it during startup.
