Weird!!! I have been playing with the ALC622.kext that RGGG has posted. I have not used the DSDT directly, because that would, as flip360 already experienced, cause a KP. I have instead taken the HDEF part that I see in that DSDT, and replaced the HDEF section of my system's DSDT.

I have installed the ALC662.kext, and have used the AppleHDA (original from the 10.6.2 update) ... didn't work and nothing has been changed on the system.

Then, I used a patched AppleHDA in combination with the same ALC662.kext. That patched kext with itself doesn't work either for me, even though I tried to patch the binary according to the guides that are going all around. But when combined with the ALC662.kext, it will HANG my system up.

Now, I can't boot it anylonger. Care should be take when using it ... this is the second time I got this hang-up, but this time, it is more serious, because I can't revert the system to a working state.
