If you have the chips, super glue them back.
I enlarged 2 holes on my bass a long time ago for RadioShack switches. I've decided that was stupid and filled the holes with epoxy from a fiberglass repair kit. Now, I just have to paint over them with black paint and decide if I want to re-drill for tone pots/pre-amp or just rock 2 volumes.
EDIT: ^^^ that's only if you make the problem worse; like Hammerhead said, just don't worry about it... Hammerhead said... IT RHYMES!!!
