Are we talking for 3e? Not much (aw, heck, there wasn't much for 2e FR either).
For FR3e: City of the Spider Queen, Pools of Radiance: Attack on Myth Drannor, and Into the Dragon's Lair.
City of the Spider Queen looks very good. Higher level, lots of detail and maps. May have a questionable premise, though (won't say - spoiler).
Pools of Radiance: Attack on Myth Drannor is mediocre. Decently written, with some good NPC motivation/details. However, the maps are absolutely *abysmal*. Prepare to do a lot of re-mapping of most locations.
Into the Dragon's Lair: I've only skimmed my copy very briefly, so I can't reasonably comment on it.
Generic modules:
I recommend looking at other threads on this board. There are some good discussions of what generic modules are good. I'm personally partial to: Rappan Athuk I,II,III; Tomb of Abysthor, Vault of Larin Karr, Siege of Durgam's Folly, Hall of the Rainbow Mage, Return to the Temple of Elemental Evil, The Banewarrens, Demon God's Fane, Sunless Citadel, Forge of Fury...
All of these should be easily fit into The North and the Silver Marches region, except The Banewarrens (I put my version in the Vilhon Reach).
