Powertop doesn't scroll within 'tunable' page

Bug Description

I'm running powertop on more-or-less stock Oneiric, and the 'tunables' page is entirely full, perhaps because it's reporting on so many cores (it's an 8 thread Intel i7).

Unfortunately, I'm pretty sure there are extra entries but the terminal cannot show them and there appears to be no way to page or scroll within the tunables page. Dragging the terminal window and refreshing gets you a few more lines, but it's impossible to make the window big enough to see all of them. When scrolling the highlighted line to the bottom, it eventually arrives at highlighting the VI/EMACS style command line, and hence won't scroll further.

On the plus side I think the 'bad' entries are pushed to the top.

Can I suggest some kind of scrolling behaviour or some simple and intuitive interaction to page? Perhaps it's there but I can't trigger it.

Hi PowerTop-Mailing-List,

I have a problem with powertop: It doesn't scroll in "Tunables".
I sometimes have to deactivate the powersaving of my WiFi card.
This isn't possible if I can't find the option (because it is out of view in my Terminal)

Best regards

the issue is still present in powertop 2.1-0ubuntu1 (compile date Aug 23 2012), I'm running Kubuntu 12.10 with kernel 3.5.0-31-generic.
Is there any chance to get this fixed?
I've found this relatively old patch on the powertop mailing list but didn't test it:

At least in Ubuntu 14.10 and 15.04 this bug is fixed. Could someone confirm this for 14.04?

If It is fixed in 14.04 this bug should be marked as "fix released".
