OK so, currently there is a script which will allow you to "temp" Overclock your D3! the instructions are here:
[OVERCLOCK]XT860/XT862 Overclock - xda-developers
Following this threads instructions you can set your clock speed via a script which will allow your processor to run at either 1.1, 1.2, or 1.3 ghz!
However this only lasts until you either reboot or make any change whatsoever to your clock speed (via setcpu Gov's or what have you...) if you follow the suggestions of some of the comments, they give instructions for the logical steps of how to make this as permanent as possible using a simple script set to "run at boot, and run as root". In a sense this makes it a permanent OC ... however you will be forcing your processor to run at a constant overclocked speed... not necessarily an issue but it does negate the battery saving governor setups that some of us like to use...
