Okay, I have a question. What is the lowest voltage profile in which I can play/record HD videos flawlessly? I need something that has 600 MHz for all of its steps, something like:
# kernel configuration file generated by /usr/sbin/kernel-config
MINFREQ=500
MAXFREQ=900
FREQS="0:25,90 500:49,500 550:51,600 600:51,600 700:51,600 750:51,600 805:51,600 850:51,600 900:53,600 950:54,500 1000:60,500 1100:72,520 1150:72,520 "
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0
GOVERNOR=ondemand
IGNORE_NICE_LOAD=0
UP_THRESHOLD=85
SAMPLING_RATE=150000
POWERSAVE_BIAS=0

...but with lower voltages.

N.B. My N900 is HW Rev 2204 so it is one of those few super natural N900s out there, it can handle the lowest of voltages.
