Hey,
Using hot glue to fix that little chip on iBook G4 isn't what I'd do - it'll just fail again within time and be a right royal bugger to remove (and you'll probably rip off the little chip getting the glue off). I was recently given the same specced iBook G4 1.07 - in pieces - same issue with the little chip (someone had already tried to fix it with a heap of BlockBuster video cards - layer upon layer as it got worse!), and just touched each leg for ~ 3 seconds @ 350 - 400deg C. This was using a not-very-fine-tipped iron point and wasn't at all hard to do, and it's been fine ever since.
Unless you can solder it back, glue/shim/clamps will work for a while but can never be considered 100% reliable in the long term.
