And this.

Sandra Bullock and Leonardo DiCaprio each donated about $1 million for disaster relief following the recent tsunami in Southeast Asia. The Steven Spielberg family donated $1.5 million. Jet Li donated more than $125,000; Jackie Chan added at least $64,000. Among several dozen rock bands which donated proceeds of their concerts or made outright donations, U-2 and Linkin Park each donated $100,000; Ozzie and Sharon Osborn donated almost $200,000.

So I think it is far to say that many celeb's with money do make very large donations.

I am struggling to find any large donations made by Bob Geldof himself. Maybe someone can help me out.
