Sorry, I was testing Oneiric at the time I responded. gnome-panel has
been moved to universe in 11.10:

If you do go that route, be sure to generate a 'marking' list & then you
can reinstall any packages that get left out. See:

<http://helpdeskgeek.com/linux-tips/reinstall-your-ubuntu-apps-after-a-fresh-reinstall/>

for an example in doing this with Synaptic. Of course you can easily do
this via the command line as well:

$ dpkg --get-selections > ~/my-packages
and to put them back:
$ sudo dpkg --set-selections < my-packages && sudo apt-get dselect-upgrade
