By default ACPI is disabled under core. The line should look something like this: "kernel /boot/vmlinuz-2.4.22-1.2194.nptl ro root=LABEL=/ hdc=ide-scsi rhgb" you should change it to look something like this: "kernel /boot/vmlinuz-2.4.22-1.2194.nptl ro root=LABEL=/ hdc=ide-scsi rhgb acpi=on" You should also disable apmd and make sure that acpid is running.
