Then these problems are not same, İsmail's problem was an ACPI one and im sure
that solved but yours seems a userspace problem (hal checks /proc/acpi/info
and kpowersave uses hal) introduced by "/proc/acpi/info deprecated
by /sys/firmware/acpi/info" [1]. You can try untested attached patch against
hal-git tree, so i'm adding hal list into CC also.
