I got 'em!
I didn't find them on the net anywhere, but I reloaded my (J) save and found that you could see the passwords you entered in there in a log of the passwords. On the top screen you can see the actual image of what I drew back when I did find the touch screen passwords. So I traced them off the top screen and tried them on the lower screen in the (U) release and they're the same!
So I scanned my tracings and will post them here. Sorry the scans are a bit weird, I did them rather hastily. The sword one is by far the trickiest. The large space below the image is the bottom of the image (so in the scan the sword is upside down from the others).
Edit, couldn't attach it to the post so I put it in the
downloads section under "other useful tools"
