Ok, I am running Droid 2 overclock and it happened to me once. This is what I did, and have not had one single relapse. In my profiles, I went and set one of my profiles to 1300Mhz and 400Mhz with "Screen On", and set that to 100%. Here are my profiles, and they do work very well for me.
100% Charging AC/Full 400 MHz - 400 MHz
100% Screen Off 900 MHz - 400 MHz
100% Temp > 40c 900 MHz - 400 MHz
100% Battery <40% 900 MHZ - 400 MHz
100% Screen On 1300 MHz - 400 MHz
Lastly, I am running LV 1.3 GHz, and battery is good so far, and so is the temperature.
