Subject: [PATCH] eeepc-laptop: enable camera by default

From: Pekka Enberg <penberg@...helsinki.fi>

If we leave the camera disabled by default, userspace programs (e.g. 
Skype, Cheese) leave the user out in the cold saying that the machine "has 
no camera." Therefore, it's better to enable camera by default and let 
people who really don't want it just disable the thing.
