I'd have said that a published setting is just personalized, rather than homebrew, no matter how much you change it. At least until I joined my friends "Greyhawk" campaign in 3E.
I asked where we were based, and was told Verbobonc, so I wrote up a character that was born in Hommlet before the first rising of the Temple of Elemental evil, and became squire to a Knight of the Hart during the battle. I eventually earned my spurs (and became a paladin of Heironious), and returned to Verbobonc to serve against any future rise of evil. I explained my background to the DM at the start of the session, so that he could introduce me at his convenience.Everyone stared blankly at me... no one had read ANYTHING about Greyhawk, despite playing in it for almost a year! The DM had gotten the map, and other than a quick glance at Verbobonc, just made everything up (He didn't even know who Iuz was!)...
Now I pretty much consider the defining line where you deviate from canon. If you want to run a game based on canon up to a certain point, then ignore later events, I think that's still just personalizing. If you decide to change things that lead up to your starting point, you're probably in homebrew territory. Of course, this is all just semantics anyway
