When I was running Gnome, I had installed a monitor in the system tool bar that displayed the current clock speed, as well as let you select the priority (performance, on-demand, etc.). After I had installed KDE, that bit of Gnome broke (even though the two window managers shouldn't interfere with each other, this time they did) so I couldn't click on it to find its info, and I can't remember where I got the monitor from - I'd like to have the same thing working in a panel in KDE.
I thought it was gnome-system-monitor but that wasn't it. The one I'm after is shown on the left of the system monitor in the toolbar below:

Does anyone recall where this can be found, and if it will run in KDE? I've had a look at the widgets list and downloads but can't seem to find it.
Thanks.
