Power management on Advent 4211

Found what looks like an updated power management kernel extension that specially fixes the iTunes choppiness and hopefully crashes, VoodooPower. Found it in this forum topic, which seems to have several suggested post-install instructions.

So far no choppiness in iTunes, and it hasn't crashed, but then I only just installed it.

Voodoo power management to replace coolbook

Somewhere along the way Coolbook, which I paid for, has stopped working. I checked and there are kexts that allow the speedstep functionality to work without CoolBook.

The kexts changed their names to VoodooBattery.kext and VoodooPower.kext, but I downloaded and tried them to see if they stopped the fan going a lot, kept the temperature down and extended the battery life.

Edit:

Found more in dept discussion here:

Have had a couple of crashes since, on both AC and battery power. Maybe need to change plist file referred to in first forum topic.

Noted a few problems: Dvorak keyboard needs to be re-added after crash, I have two battery icons on the task bar, and (this is weird) when on Dvorak keyboard the Ctrl key combination now works on the Dvorak key (like in Windows) not the qwerty key (as it used to). But now realise there are two Dvorak keyboards - the one that says (option key symbol) Qwerty is different and that explain the difference.

Helpful post:

you can add the bootflag via osx86-tool, which you find here: http://pcwizcomputer.com/osx86tools/
download it, start it, click on "add efi strings / boot flag", fill "FSB=133 memoryType=19 memorySpeed=677" (without the " of course ^^) in the top left text-field (should be empty), then on apply changes at the bottom.

Found a person in the second forum page 7 i think that says that it doesn't work with msiwindosx, which IIRC is what I installed - gives stuttering iTunes and kernel panics. This is what I have seen. Time to uninstall? I'm pretty sure that the problem only happens on battery power.

Found that edowar on that forum is recommending the GenericCPU ??? .kext over the Voodoo ones. Tried to uninstall the Voodoo ones and try that instead, but ended up uninstalling it too because it also caused stuttering when on battery power. There are two versions at least listed, tried this one:

Hibernate/sleep in OS X on Advent

Found I could change the HDD sleep time to 3 minutes using this command:

sudo pmset -b disksleep 3

Don't know if it works though.
