At the beginning of the takeoff roll (well below 80 KTS) crew felt a loud 'thump.'  It felt like running over a seam in the concrete.  It wasn't an unusual sound.  On climbout; the cabin crew called to say they smelled a faint odor of burning rubber in the cabin.  The cockpit crew noticed the same odor.  The odor dissipated within a few minutes.  No other abnormal indications were noted.  We began to think we may have blown a tire on takeoff roll.  The crew made a call back to the Tower to advise and have them inspect the runway.  Also called Maintenance to advise.   We consulted the QRH; which advised continuation to destination.  A call back from  Maintenance confirmed the runway was found to be free of debris.  We elected to continue to destination; and encountered no further complications.   Upon arrival; Maintenance inspection revealed that a cargo pallet in the forward compartment had broken loose and slid aft; damaging an air duct.
