Cleaning Up Unused Kernels

Does the following article still apply to cleaning up/removing old/unused kernels in 12.04 LTS?

Yes. I can't say for certain that doing this via Muon Package Manager works as it does/did in Synaptic Package Manager, but it should. I say this because I don't use a GUI package manager for installing/removing anything. I do that from the console with apt-get.

That sort of removal is very incomplete and leaves back a good portion of the old kernels.
Every kernel has four packages: (kernel 3.5.0-15 show as example)
linux-headers-3.5.0-15 (header files)
linux-headers-3.5.0-15-generic (additional headers depending on kernel type)
linux-image-3.5.0-15-generic (kernel image)
linux-image-extra-3.5.0-15-generic (extra image)

Once you have installed a new kernel and booted into it to see that it's working properly, you can remove all packages related to older kernels - generally around 220 MB for all packages together per kernel.
In Synaptic, enter your major kernel version in the search box (e.g. 3.5.0), this will show you all packages for your kernels, and not just a small part of it. You can now uninstall all packages except those four for the latest kernel.
