I'd prefer to just go with "If you're using one hand, then it's one-handed" because the whole Monkey Grip and Large sized weapons thing from 3.x really left me cold.
I dunno, I'm fine with giant-sized PCs having some mechanical benefit from being huge, but I'm lazy and figure just giving them a bunch of STR covers it enough. I imagine I'm in the minority opinion there.
I'll rule (if this is a houserule, that's cool too) that the 2-h bonus to power attack, etc. comes from using two hands for increased leverage, so you don't get the bonus unless both hands are holding the weapon.
