I have an iBook G4 and also have this problem. My computer is still stuck on that screen even when I attempt to start in safe mode

. Any suggestions?
Start up in Single User Mode to use FSCK
FSCK - File System Check (Repair Disk)
To start up in single-user mode
1. Shut down the computer if it is on.
2. Press the power button to start the computer. If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
3. Immediately press and hold the Command (Apple) key and the "s" key.
You have successfully entered single-user or verbose mode when you see white text appear on the screen.
4. At the command-line prompt, type
/sbin/fsck -fy ( don't forget the space between k and - )
5. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (name_of_volume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command you typed in step 4 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
6. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
Your computer should start up normally and allow you to log in.
