Unfortunately, I'm also learning the DSDT myself. And most manufacturers don't document anything about the devices or their methods. It's mainly error and trial, I'm afraid.

Could you send me the AMW0.kext? I could play around with it after I finish my SD card driver-- assuming my son's Acer gets fixed.
