How was the 'bump' removed from the Airbus P2F?
The A330 P2F features a fully-powered Cargo Loading System (CLS) that is perfectly capable of loading/unloading even the heaviest pallets even with the aircraft "on the tilt". Therefore, no 'tilt remedy' is required.  

Flight Global, 15 February, 2012:


  The P2F version will retain the passenger aircraft's geometry and incorporate a powered cargo loading system to enable pallets to be moved "uphill" on the main cargo deck.
