This may be one cause of extra battery drain, ideal (xlv) kernel has trouble to put wlan chip into power save mode, as dmesg contains this message repeated:
wl1251: ERROR Power save entry failed, giving up
Also based on BatteryGraph data idle power usage is at least 2x than it was with previous kernel!
idle power usage has been perfect for me so far.

Allowing user space to change the vsel column of the mpu table is trivial. It also sounds better to me than having predefined tables in the kernel. The user space program can have those tables. This patch should do the trick:
Disabling specific frequencies might not be as easy. I think that the easiest way is to add a scaling_allowed_frequencies to generic cpufreq code, rather than hacking ARM specific code.
if you can write a patch implement scaling_allowed_frequencies I'd glad to include it.
keeping the DSP frequencies variables could be useful as well.

Hello all.
Here http://wiki.maemo.org/Overclocking it says the default config to 'pmconfig file' .
It says:
clocks_off_while_idle 1
voltage_off_while_idle 1
But i have:
clocks_off_while_idle 0
voltage_off_while_idle 0
Any ideia because of what? Anyone have it?

it contains cpufreq-info to summarize all info.

after installing the new kernel do i have to change the /etc/pmconfig to set the overclock?? and whats the best way to determine my current clock?

root
echo 250000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 599000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Download conky, it will tell you the stats..
btw, echo 250mhz min does not work with ideal kernel

ULV & LV by titan
I discovered something about my device : using the ULV kernel it bricks when using the 850Mhz max freq but boots up normal when raising it up to 900Mhz.
been using it for almost half an hour now and it is stable.
on the other hand the LV kernel works great at any speed - so going back to the LV kernel

There are five different titan-kernels stock/lv/ulv/xlv and ideal. You need to download a different kernel depending what type of voltage you want.
The mhz or "overclocking" is decided in the /etc/pmconfig. However you could try a mhz before you decide which speed to settle with. With the command i wrote in my last post. And yes, the ideal-kernel should be runing with 500 as min_freq.

idle /overnight, icq on, mail retrieval every 30 minutes/ ... with titans xlv kernel, it eats about 20 percent ... weird
looking forward to seeing that "promised" titans kernel with customazable voltage anyway
