I think I have Solved the Issues?
OK after much tinkering the last 24 hours I have done some things to my phone and now the settings for screen off 400MHz. I did a few things so I will put my steps here and let me know if it works. "Note I did a lot so I am putting it all to be sure it works because its hard to narrow it down"
1. Make a back up of your Rom using bootstrap
2. Wipe phone and reload your rom from backup copy
3. Install the following

Note> the info for step 3 is all here

FOR LIBERTY ROM ONLY
4. After the Phone has booted up go to droidx over clocker and use something like the profile below.

(I use Medium power frequency)
5. Fix Permissions in the DX over-clocker app and if you would like set to fix every-time on boot in Liberty toolbox
6. Reboot and test it out
I also wanted to say that the reason most of us are trying to do this is because we want everything on our droid x with no compromise if you have Liberty rom and this was to save power I recommend JuiceDefender. Its a bit expensive but if you want to make the phone last longer when your not using it kind of like under-clocking your data usage to help your baby sleep. In conjunction with actual under-clocking and knowing when to flip JuiceDefender on and off your phone will last for a very long time.
Please let me know if this Helps or if you have any questions!
