Everything. Voice, file transfers, ingame chat (I tested with Sauerbraten and CS 1.6).
What does not
Names in list are still white. When someone chats to you while in-game, the normal message box pops up too, resulting in the game minimizing. Solution is to open up a conversation window with all the people you might speak to or might speak to you before you play and it will work fine.
Xfire does not minimize normally, it has a bug with this in Wine. It simply becomes a small black box which sits in the lower left of the screen, still not that intrusive but just annoying.
What was not tested
Group chats (but they should work).
