Patch Removal
Playstation 3 - From the XMB navigate Game->Game Data Utility->Fallout: New Vegas->(X)->Delete->Yes. (NOTE: The size is ~4GB this is because this is all the game data that was installed when you first played the game. The patch downloaded from PSN was implemented with this data. You must delete all this data to remove the patch. The game will reinstall itself next time you load it up. This will NOT delete your game saves.) Doing this will not remove the pre-ordered content because the pre-ordered (DLC) is a seperate file. After removing the game data and installing it again: When you attempt to load from a game save the game will warn you that you are missing content. Select yes on the prompt and you should be fine.
