FYI, kernel-power and kernel-power-settings have finally made it to extras (stable).
The new wiki page for the kernel is http://wiki.maemo.org/Kernel_Power
(at the moment just a copy&paste from the Overclocking page).
I'd appreciate if you could add more info, for example about iptables, ext4, USB/IP, evdev, PPTP, cryptoloop and kexec support.
There were some requests from people who would like to use the additional features of the kernel but don't want to risk losing their warranty by installing a kernel that is overclockable.
I consider uploading another package that does not have the OC patch.
If possible it would be only the kernel package and share the modules and flasher package.
But it may lead to too much confusion with all the different kernel version.
What do you think? Any ideas for a good name?

Yeah, I just noticed this too.
Actually, it's related to the DSP. When the DSP is busy (ie. during splash screen, playing videos, and MP3s (I guess)), it either starves the CPU, or shares vdd1 with it, and undervolts. If you're able to check the dmesg buffer, you can see DSP sync errors when it happens.
Here are my new values that appear to be stable while playing video:
Interestingly enough, the CPU enters sleep state during video playback, so the first voltage is critical. While it's otherwise stable with 15 as the first value, it locks almost immediately while playing video. It makes sense, I guess.Code:20 20 25 30 35 38 43 45 48 51 54 56 60 65 72
The main problem was voltage too low at 250 and 500mhz.
I don't think we can do better than this for ultra ultra low voltage.

Hey do I also have to edit this line's values in the kernel text file?
DSP_OPPS_RATE="90 90 180 360 400 430 430 430 430 500 500 500 500 520 520"
If so what do I put for the values? Or could you show the entire text of your kernel file?
VDD1_OPPS_VSEL="0 20 28 33 38 38 45 45 48 48 54 54 60 72 72" DSP_OPPS_RATE="90 90 180 360 400 430 430 430 430 500 500 500 500 520 520"

Wi-Fi transmission power: 100mW
Power saving: On (maximum)
and my ping times are in range from 3 to 5ms to WiFi router and around 22ms to my home server.
EDIT: it depends from other traffic in network and router proximity. I discovered that in calm state I have 30ms.
