My kid has an iPod touch that has locked from too many attempts to enter the passcode for 22 million seconds. He did this before and I connected to iTunes and it successfully unlocked it. However, I have subsequently upgraded the computer that iTunes was on, and, although the original hard disk is readable, I can't boot it, and can't seem to repair it. Can I install iTunes on the new computer and copy over some key files or something like that from the original iTunes install to get this device unlocked?

Maybe you could try restoring the iPod touch? If you enter DFU mode (described below) and click Restore, you'll get the iPod back up and running.
To enter DFU mode...
The iPod touch should subsequently be available in iTunes as if it were in recovery mode; you should now be able to restore the device.
