Stopped following this thread about 200 pages ago, but I am back!
Loving power kernel, overclock, and PR1.3. I was struggling with voltages and min freqs though. I settled on an on demand approach with about 5 beecon widgets to dial in what I want at the time.

Was using a lot of 125 to 805 mhz starving as my basic setting with 125 to 1100 ideal as my performance setting. Would revert to starving 125 - 600 for extended life.
That was very jerky, so I tried bumping up voltage for slight improvement and still good battery.

Now trying 500 - 805 starving, 500 - 900 starving and ideal, and 500 - 1100 ideal.
Still seems a bit more stable. Will see what battery is like.

PR1.3 has helped battery quite a bit. FYI, i simply reinstalled power kernel after update with no ill effects. All me kernel config files stuck around or were restored after update.

BUT THE QUESTION IS: All the voltages, min freqs, max freqs, it makes my head spin! Is there a silver bullet overclock solution (well, stock, duh! but what else?) or do I have to rigorously test them all?!?!?
