.config is 'make rx51_defconfig' from v4.6-rc4-n900-camera branch, with 
added:

CONFIG_VIDEO_BUS_SWITCH=m
CONFIG_VIDEO_SMIAREGS=m
CONFIG_VIDEO_ET8EK8=m

For some reason I have to do 'modprobe smiapp' after every reboot, 
before using cameras.

After taking a nap, a question came to my mind - what is that device 
you're using? As some early board versions use VAUX3 for cameras as well.

awk '{ printf "%s ",$1 }' /proc/modules results in:
