Don't know what you mean by a Powerbook 3G.
With those computers that came with installation DVD/CD disks you can start up from the installation disk and reset the password
- Start up from a Mac OS X Install disc (one whose version is closest to the version of Mac OS X installed). Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C). Or, you can use Startup Manager or the Startup Disk preference pane to select the Install disc.
- Choose a language, click the arrow button to continue,
- Mac OS X v10.6 or later: Choose Password Reset from the Utilities menu.
Mac OS X v10.5 or v10.4: Choose Reset Password from the Utilities menu.
Mac OS X v10.3: Choose Reset Password from the Installer menu.
Tip: If you don't see this menu or menu choice, you're probably not started from the disc yet.
Note: The default keyboard layout is U.S. English while started from the installation disc. If you use a keyboard layout other than U.S English, use the Input menu (the flag icon on the right side of the menu bar) to select the desired layout before typing a new password.
- Select your Mac OS X hard disk volume.
- Select the user name of your original administrator account.
Important: Do not select "System Administrator (root)". This is actually the root user. You should not confuse it with a normal administrator account.
- Enter a new password.
- Click Save.
- Click the red button in the upper left corner to quit the application.
- Choose Quit Mac OS X Installer... from the Mac OS X Installer menu.
- Click Restart.

Did anyone notice that the OP says he has System 9.2? Sounds like a G3 PowerBook.
The only way around this is to boot from another partition somehow. An OS 9 boot CD is required, after which the keychain contained in the System Preferences folder can be trashed. With no keychain, no password will be required to log in.
If it's a Pismo or later then FireWire is an option.

Good call. When I overlook details I remind myself of these quotes.
- understanding the question is half the solution.
- when everyone agrees on something, you can be certain they are wrong.
- put mind in gear before answering.
