With Core 1 you must edit your grub.conf file and add "acpi=on" to the
line that loads the kernel. 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.
