kizwan:

You should see an AMW0 device in your DSDT (see this post by Carlos, the writer of the acer_acpi implementation).

My guess (without looking at your DSDT) is that the device control function keys may be implemented in DSDT block that checks whether the OS is Windows. Does your DSDT have calls that only do things if the OSI is Windows? Mine does.

If so, then it may be *possible* that you can enable the Windows-specific parts, and then call into the AMW0 device defined in the DSDT from a simple kext. Perhaps that is what superhai was doing.
