Yes my sound chipset is ALC 888, my processor is a quadcore Q6600, my graphic card is a GTX280 with 1Go ram, and I have 2 SATA hardrive, only one is used for macosx. I got 2x2Go of DDRII Ram.

you would be nice if you improve my DSDT, but for now everything is OK, sleep, shutdown, reboot, sound, grpahic card, using voodooHDA, NVEnabler, and I also installed standard leopard Kexts from iBoot CD from tonymacx86, I can give you the list.

The onlything that is not perfect is when I close my session and login with another user, system get slow, especially graphics...

It could be that NVenabler unloads across logout/login and that's why the system gets slow.

Wait a sec, 'standard leopard kexts' ? What do you have, Leopard or Snow Leopard installed?

sorry, I meant snow leopard sorry. I uses this tool:

Maybe nvenabler unload when changing users, but I also experiences troubles with the mouse... but it's no big deal, We're not changing user all time... and I used it all the day yesterday, installing apps, listening MP3, got no troubles.

Do you have IORegistryExplorer? An App, part of xcode tools.. Can you save a dump from it if you have it ?

I download this tool, and it does the same thing as ioreg, that is hanging with using 100% of the CPU. But is you want my DSDT, I posted the patched one in this topic, I can also post the original one if you want.

I guess that my DSDT is not working after all, It may have been ignored, because I made a permission repair, and now when booting I got a message from chamelon : ACPI version 2 not found, but I'm still able to boot...
I'll look for this, but if some of you guys have an idea how to do that thad would be great.

Ok. Don't worry about acpi, its just a notification. Your dsdt should be loaded.

What are all the kexts that you have installed, both yourself and via the package you used ?

---

I have installed:
fakesmc
IOAHCIBlockStorageInjector
JMicroATA
LegacyAppleRTC
NullCPUPowerManagement
EvOreboot
VoodooPS2Controller

NVEnabler
VoodooHDA

I will now try to patch the cmos reset fix in my DSDT according to the thread in this forum.

Ok, I patched the RTC part of the dsdt by replacing length from 4 to 2, it's working, but if some of you knows a way to disable chamelon debugging, so that I have not to see the message and press a key to boot it would be perfect.

Thanks for your support guys.

solved this:
I used a RC5pre6 version of chameleon, I installed RC4 and now its perfect. It's also recognizing the right frequency of my RAM (was 667Mhz, no its 768, and 768 not 800 because shitty motherboard won't let me set the SPD value I wand when overclocking my processor, so I set a lower value... but that's not related with mac)
