The problem is as follows:

sudo modprobe acer_acpi

FATAL: Error inserting acer_acpi (/lib/modules/2.6.17-10-generic/extra/acer_acpi.ko): No such device

dmesg | grep "acer_acpi"

[ 2873.793122] acer_acpi: Acer Laptop ACPI Extras version 0.4 [ 2873.793136] acer_acpi: No WMI interface, unable to load.

As per your README:

1. Acer Aspire 5002
2. Attached is what I belive to be my ACPI DSDT file dumped via acpidump

I suspect this problem has something to do with:

line 72 of acer_acpi.c:

define WMI_METHOD "\_SB_.AMW0.WMAB"

Thank you so much for your efforts, I wish I knew more so that I could help...

Hi benikaj,

unfortunately this is a known issue, the 5002 does not have the ACPI interface acer_acpi uses, and some research 18 months ago couldn't find an equivalent interface in the 5002 DSDT. Several of us went looking, and had no luck.
