Is that mean the error is not false alarm? Thanks!

Opps, the same error occurs after change, but as you say, I try it in DSDTSE, it is no problem, so I just use your one. Thanks so much, anyway!

For using the UseKernelCache=Yes in chameleon, you must move all kext in EE to SLE by using kext wizard or any apps like that. I read from web that if UseKernelCache is enabled, then it will ignore the kext in the EE, so the move of kext is a must. And I also did it and now is ok using the UseKernelCache=Yes.

If you are still on Chameleon under 1xxx, then the boot.plist filename is different. It is still com.apple.boot.plist, but when upping to chameleon over 1xxx, the boot.plist filename is redefined to name org.Chameleon.boot.plist. I guess that your instant reboot maybe due to without renaming the boot.plist file?

For the FaceTime to work properly, only the Chameleon v2.1 svn r1493 should be used, I try many, only this version can properly connected the FaceTime server and authorized.

Just some experiences shared,

1. I tried this ACPI Backlight and I'm having brightness control in my display settings now, but changing it makes no difference. I think my DSDT has to be corrected. Maybe you can give it a try and tell me how it worked.

2. For the webcam you have to use Camera Control. You can start it before or after starting Photobooth et al. and you'll get a picture (if your webcam is recognized at all, which you can do by adding correct ID's in the iSight next).

3. Audio really needs to be fixed. Since I've been searching so long now, I think it is impossible to add bit depths in VoodooHDA. That audio out is working correctly indicates that it has something to do with incorrect nodes for the other devices. But don't ask me how to do this. I tried patching AppleHDA with codec dumps but still no success.

1. For the backlight control, you don't need to use that ACPIBacklight.kext, just add few lines to the DSDT, then u get the brightness control and also on-screen display(the sun), but with another combination of key( Fn+Home = Increase Brightness, Fn+PgUp = Decrease Brightness). However, we only have 10 step of brightness, so just half of the meter will be used for the on-screen display. The line to add just after the (before the Device LID0)

Scope (_SB)
Device (PNLF)
Name (_HID, EisaId ("APP0002"))
Name (_CID, "backlight")
Name (_UID, 0x0A)
Name (_STA, 0x0B)

2. The webcam I use the cam twist to solve it, since the cam control need compile? I don't have the Xcode installed.

3. Audio is still no HDMI sound out, maybe later get a dump from linux will help.

4. For the USB2.0-CDW card reader, I will give up. This devices seems no successful record so far.
