Joystiq caught up with Steve Papoutsis, the game's Executive Producer, and he explained that his team feels very strongly that everyone should be able to enjoy their game:

Hearing the call of disabled gamers asking for customizable controls, Visceral Games and EA jumped into action and are currently working on a patch to offer this for players. Visceral Games, the makers of the recently released and well-received, Dead Space 2 are one of those companies. Thankfully there are companies out there that understand the needs of this portion of their audience and are willing to help. But what if you had some type of disability that prevented you from playing games in that way? Would you give up games entirely, or would you try to find a solution that would still allow you to continue to enjoy this hobby? Most of us would probably say that we would find a way to still game. Many like to relax on the couch with a controller in our hands or sitting at our computer desk playing with a mouse and keyboard. One aspect of gaming that most of us take for granted is how we play our games.
