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 ....)
