You should inspect /var/log/messages and /var/log/dmesg for any entry
regarding acpi. Perhaps you will find an error message. If you don't
find an acpi message, probably there is a typo in your grub file. 

It should read like:

title Fedora Core (2.4.22-1.2129.nptl) ACPI
        root (hd0,2)
        kernel /vmlinuz-2.4.22-1.2129.nptl ro acpi=on
root=/dev/Volume00/Fedora
hdc=ide-scsi rhgb
        initrd /initrd-2.4.22-1.2129.nptl.img

(the two lines after kernel .... being on the same line as kernel ....)
