View source for Reviving XO1 camera

=== Paraguayan attempt ===

The problem with the camera seems to be the xf86-video-geode module. The cafe_ccic module is loaded automatically. Cheese or recordactivity crashed right before show any picture. Then I tested remotely with ssh -X and it worked for olpc and root and it works.

This test was done with:

* XO-1 kernel: 2.6.31_xo1-20091214.1334.1.olpc.49c30d0
* os10

Even if it works remotely, there are a lots of warning messages on the /var/log/messages:
