How to return back to ubuntu 10.04 netbook interface in 10.10?

[Rhys]

Ubuntu 10.10 netbook edition.

Unity is really slow on my model: HP Mini 5101, so I decided to remove
it with other ubuntu-netbook related packages.

When I return back to ubuntu-desktop session, I installed maximus
package and want to achieve the same effect as classical netbook
interface. After moving the bottom panel to the top and adding some
needed applets, I got a screen as http://imagebin.ca/view/6hunpd.html

But, how to hide a window's titlebar when it is maximised?
