I suppose we need check each device for optimal frequency/voltage for best result and stability, but it should by mostly same. In any case at first we should check and fix frequency scaling and push it in to main branch. Then we can adapt it to other device.

Is 1.1V lower stable voltage on 240Mhz?

I was about the backlight-patch. I thought that it was clear because I cited just that part.

Yes, but 1.0 was not. I was mostly curious to see how important voltage was to runtime.

The backlight patch is already committed, and (as per the first post), specific to the Zip.
Mihail Zenkov:
New version with frequency scaling based on as3525v2-cpufreq-v11.patch.
