Modifier Key Mapping Not Working

When I'm at home, I connect my MacBook Pro to a 24" LCD, along with an external keyboard and mouse. One of the small features I was looking forward to in Leopard was not having to go into System Preferences and switch the modifier keys to correctly work with my external keyboard, but I've discovered that the feature isn't working. I choose "USB Receiver" from the keyboard drop-down, re-map the Option and Command keys, click OK, and close SysPrefs. Nothing has changed; the Command key on my keyboard is still performing as Option and Option is still Command. When I go into the Keyboard & Mouse section of SysPrefs, the Modifier Keys pane is back to it's default values. I'm wondering if this is a bug in 10.5 that will be fixed with 10.5.1, or if it's just my keyboard. Any tips would be greatly appreciated!
