Yes i have used this app in kk's loaded roms. Once installed and soft reset u will see it in start menu programs. Create a profile for tom tom 7 and set it to rotate and only check 270 for reverse landscape screen on left buttons on right or 90 for buttons on left and screen on the right. Program runs in the backround just like g sensor but its easier to use and setup with specific apps only so that it does not mess with normal operation.
Instructions from xda

Works like a charm for me and if u want it to do this automatically just add it to your startup. Program uses verry little ram yet highly configureable.
