I had an app I think called widgetsoid or something to that effect where you could place a widget into your notification panel.
However with that being said I agree with the previous posts, I strongly recommend rooting and installing MIUI as your ROM especially if you want power controls in your notification panel. I have had Liberty, Cyanogen7, and ended up with MIUI.
RSD Lite is nothing to use just make sure you follow directions. I actually had to SBF my phone this morning which only took about an hour because I had to download the files, and replace all my files. I know it sounds tedious and a long time but the payoff of having a better phone is well worth the hour hassle I had SBF'ing this morning.
If you have any questions or need help please feel free to shoot me a PM, I will be more than happy to help out.
