No, the PWC driver is not used on the XO.  The OLPC camera driver driver
can be found in two pieces:

	drivers/media/video/cafe_ccic.c		(the controller driver)
	drivers/media/vidoe/ov7670.c		(the sensor driver)

What you need to do, though, is to employ the video4linux2 API to adjust
the brightness control; that will disable the automatic settings.
