Oh, and on another note (regarding Galactus's Hunger), did anyone read the comic in which the Abstracts had a meeting and discussed the role of Galactus in the universe, and an agreement was reached between Galactus, Death and Mephisto. I think it was called "The Gathering" or something like that. It was sort of like a preface to the origin of the Silver Surfer story.
Anyway, they all meet before Living Tribunal because Eternity, Death and Mephisto are worried Galactus's role as devourer of life energy infringes on their territories. To appease them, Tribunal ordained that Galactus (at this point, though it was later retconned) would not consume the life energies of sentient beings, but only that of planets suitable of sustaining life. Galactus then mentions his plans of taking on an apprentice (Surfer) which was discussed with Eon (who appeared in the form of a tree). Mephisto and Death take issue with this, so Tribunal allows them to make addendums to the terms of Galactus's role in creation. Death's request is that Galactus's hunger is never satiated and he will always need to consume the life sustaining energies of planets (and in so doing, would destroy more planets and cause more death), and Mephisto simply asked for the ability to torment the soon to be created Surfer (whom Eon had a signifigant role for in future events of the universe).
The agreement is reached, Tribunal waves his hand, instills the hunger in Galactus, and the meeting is adjurned. The next panel shows Galactus leaving the meeting and heading for Zenn-La.
This account is from memory (I'm at work and don't have my comics), but I beleive that is originaly why Galactus hungered. What it was changed to for current continuity is unknown to me because Marvel has intertwined A LOT of inconsistencies in their character's histories.
