Hi there folks :)
I was finally able to get qe&ci work on my laptop an asus n53jl (just for the intel hd) so i'm using 10.8.3 as main os... but i'm noticing that the temperatures of the cpu cores are too high around 70° idle and grows to 100° just watching flash videos online, i think it's crazy...
i've used nullcpu before in the extra folder, but i thought it was better to use a patched version of the appleintelcpu in S/L/E but the cpu temps are the same, these are my system info...

Chameleon v2.2 r2189
Kernel flags: -f
Patched AppleIntel*FB
Natit
VoodooHDA
SleepEnabler (sleep do not work anyway)
FakeSmc (latest rev.)
Compiled Dsdt (just errors fixing no patches)

Hope someone can help :) THX :)

here a screenshot...

You need to patch your DSDT and generate c and p-states to enable speedstep using Apple's stock CPUPM.

Patches depend on the system specs.
Please upload your DSDT and tell me the specs of your system.

Thanks for your time, really friendly, this is the dsdt i'm running 10.8.3 on a i5 460m, do you need to know something else?

Give this DSDT a try.
And don't forget to enable c and p states generation in chameleon.

tried... temperatures are still high 83° right now, the only benefit seems to be that now it goes to sleep... can't wake anyway, i think it's the dual video card optimus stuff that activate the nvidia gpu when waking, i'm still stressed by the temperatures, i would like to have even sleep, but i don't really care... any idea?

Could you please extract other ACPI tables in Linux (live CD would do) and upload those? Thanks!

BTW you have a nice desktop, could you share the link? :)

About the temperatures i was thinking that it could be the optimus setup, i've read somewhere that's is possible to tweak the dsdt to disable the nvidia card, Dr. Hurt can u please add that patch to the dsdt you posted before?

OK, is the Optimus disabled now (check graphics section in system info app). It should no longer be listed there.

What are you using to monitor your temps?

Please install the HWSensors attached below, and tell me if speed step is working. You should see multiplier and clock speed changing.

Installed and checked and yes it does change, the multiplier sometimes is at 9x and sometimes is at 20x and the clock speed bumps from 1.26 to 1.80, just this nothing random... it seems that its not working as it should

The tables can be extracted in Windows too. Tables extracted in OS X, may not reflect the actual situation (DSDT at least). Not that it is only Linux feature, it's just my preferred weapon of choice :)

BTW thanks for the pic,
