I've gone through my photo archive and these were the places that served some kind of (free) bread service with the meal.
Signatures: Narcoossee's (loaf), Artist Point (loaf), California Grill (sliced), Citricos (loaf), Jiko (biscuit-like), Yachtsman (biscuit-like)
In Park Signatures: Le Cellier (breaksticks and rolls), Hollywood Brown Derby (rolls), Monsieur Paul (baguette)
Resort Non-Signatures: Captain's Grille (sliced bread), 'Ohana (loaf), Raglan Road (soda bread), Grand Floridian Cafe, Olivia's (loaf)
In Park Non-Signatures: Les Chefs (a baguette), Via Napoli (upon request, sliced), Tutto Italia (mixed), Be Our Guest (rolls)
I didn't see any photos of bread in my collection for Sci Fi, Yak & Yeti, Portobello, Flying Fish (but that struck me as odd), Rose & Crown, CRT, or Rainforest Cafe.
